Lewis Structure (6): Nitrite ion A simple way to draw the preferred Lewis electron dot structure for the nitrite anion. I simply draw the valence electrons around each atom and place the extra electron on an unpaired electron. When there's more than one unpaired electron, I put it the most electronegative atom. Then, I form bonds to make each atom as "happy" as possible (ie. complete octet). :) I prefer this method to the "add up all valence electrons + add/subtract the charges + distribute accordingly" method that is often taught in general chemistry textbooks. This method doesn't require math or memorization, and it helps you understand formal charges! Oh, it also helps you draw a preferred Lewis structure (with the least amount of formal charge separation) on the first try..... Try this method to draw the preferred structure for sulfate anion (SO42-).

Understand How Free Radicals Works and How to Minimize it. [I do not own this video] Do you know Oxygen, our life giver is also our mortal enemy? As part of life, our body wear & tear that literally leads our body to disease states. Free radicals are molecules that have an unpaired electron. They are highly unstable and extremely short-lived. They are extremely volatile and reacting aggressively which cause damage to our cells. They are formed from the process of respiration where transfer of electrons from one molecule to the next. Free radicals are inevitable, as we are exposed to environmental pollutants, industrial chemicals, agricultural pesticides, cigarette smoke and radiation. Even vigorous exercise will release a damaging flood of free radicals that can injure your cells if they're not protected. This video shows how free radicals turns the cut apple brown when exposed to air and the best way to minimize its damage is to have potent antioxidants to protect it.

DNA polymerase "DNA polymerase adds nucleotides to a growing DNA strand, guided by the sequence of the template strand. The growing DNA strand is assembled in the 5' to 3' direction with the appropriate base pairs formed at each position. Incoming nucleotides are added to the free 3' hydroxyl group that is presented at the end of the growing strand. The 3' end of the growing strand is positioned in the active site of DNA polymerase. Catalysis is carried out by two highly-conserved aspartate residues and several crucial magnesium ions. The correct incoming nucleotide, deoxyCTP in this case, is selected by the next unpaired base on the template strand. The incoming nucleotide is added to the growing strand. A new covalent phosphodiester bond is formed that extends the length of the growing strand by one nucleotide. The polymerase moves down the DNA to the next unpaired base on the template strand, and the catalytic process is repeated."

Chemistry of molecules with spin: Aiming to develop organic magnets and new batteries The Yoshioka Laboratory is studying organic magnetic materials. Magnetism has been thought unique to metallic elements, and unrelated to organic substances. Recently, however, its become clear that it may be possible to make magnets using organic materials, which have low specific gravity and are flexible. When scientists investigated the origin of how magnets attract and repel each other, they arrived at the spin magnetic moment of electrons. Such individual electrons are called unpaired electrons, and they act like tiny magnets. However, the magnetic properties of a single molecule are extremely weak. Therefore, technology is needed to align individual molecules. Q. Whether its possible to align spins in molecules is the most challenging topic were working on right now. I think one way of aligning spins in molecules is to make polymers, by utilizing intermolecular forces. Weve succeeded in synthesizing stable radicals with hydrogen bonds, and these molecules exhibit this property. Q. This only occurs at very low temperatures. But if such materials can be manufactured, its possible that theyll be attracted by magnets at room temperature, and able to act as magnets themselves. So theres the possibility of making lightweight, very flexible magnets. If this can be applied to drug capsules, for example, we expect such materials could be used to transport drugs, by placing a magnet near the patient after drugs have been administered. Also, because the oxidized or reduced ...
Molecular Orbital Theory VI: Paramagnetism and Diamagnetism Lesson on how MO theory is used to predict the magnetic properties of certain substances. A substance is paramagnetic (attracted to a magnetic field) if it contains unpaired electrons. A substance is diamagnetic (repelled by a magnetic field) if it lacks unpaired electrons.
TETRAS Tetra are species of small freshwater fish from Africa, Central America and South America belonging to the biological family Characidae and to its former subfamilies Alestiidae (the "African tetras") and Lebiasinidae. The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal fin and caudal fin. Many of these, such as the neon tetra (Paracheirodon innesi), are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria. The term tetra is not actually a taxonomic, phylogenetic term. Because of the popularity of tetras in the fishkeeping hobby, many unrelated fish are commonly known as tetras, including species from differing families. Even fish that are vastly different may be called tetras. For example, payara (Hydrolycus scomberoides) is occasionally known as the "sabretooth tetra" or "vampire tetra". Tetras generally have compressed (sometimes deep), fusiform bodies and are typically identifiable by their fins. They ordinarily possess a homocercal caudal fin (a twin-lobbed, or forked, tail fin whose upper and lower lobes are of equal size) and a tall dorsal fin characterized by a short connection to the fishs body. Additionally, tetras possess a long *** fin stretching from a position just posterior of the dorsal fin and ending on the ventral caudal peduncle, and a small, fleshy adipose fin located dorsally between the dorsal and caudal fin. This adipose fin represents the ...

Fulvic Acid & Humic Acid for Healthy Living Shilajit Fulvic Acid, The Super Antioxidant: We have found that fulvic acid is a powerful, natural electrolyte that can eradicate any form of free-radical. It can act as an acceptor or as a donor in the creation of electrochemical balance. If it encounters free radicals with unpaired positive electrons, it supplies an equal and opposite negative charge to neutralize the bad effects of the free radicals. Likewise, if the free radicals carry a negative charge, the fulvic acid molecule can supply positive unpaired electrons to nullify that charge. Fulvic acid plays the role as a bi-directional super antioxidant. Read more

Did you know about Plutarch THAT: His best-known work is the Parallel Lives, a series of biographies of famous Greeks and Romans, arranged as dyads to illuminate their common moral virtues or failings. The surviving Lives contain twenty-three pairs of biographies, each pair containing one Greek Life and one Roman Life, as well as four unpaired single Lives. He written Life of Alexander/Life of Julius Caesar, Parallel Lives!!! About GREEK and Roman GREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEK and Roman... 23 Parallel Lives about one Greek and one Roman. not 22 Parallel Lives about one Greek and one Roman and one about one Macedonian and one Roman,because Alexander was GREEEEEK.... Sorry my friend but read Plutarch he was born at 46 AD,not now!He don't know about you,this is not propaganda,this is THE TRUTH! Vardaska keep dreaming

DMT And Near Death Experiences Does DMT play a role in near death experiences? Clip from an episode of the magical egypt series featuring Rick Strassman. Endogenous DMT, produced in the human brain, is involved in certain psychological and neurological states. As DMT is naturally produced in small amounts in the brains and other tissues of humans, and other mammals, some believe it plays a role in promoting the visual effects of natural dreaming, and also near-death experiences and other mystical states. Western and Eastern mystical traditions are replete with descriptions of a blinding bright white light accompanying deep spiritual realization. This "enlightenment" usually is the result of a progression of consciousness through various levels of spiritual, psychological, and ethical development. All mystical traditions describe the process and its stages. The pineal gland is unique in its solitary status within the brain. All other brain sites are paired, meaning that they have left and right counterparts; for example, there are left and right frontal lobes and left and right temporal lobes. As the only unpaired organ deep within the brain, the pineal gland remained an anatomical curiosity for nearly two thousand years. No one in the West had any idea what its function was. Interest in the pineal accelerated after it attracted Rene Descartes's attention. This seven***th-century French philosopher and mathematician, who said, "I think, therefore I am," needed a source for those thoughts. Introspection ...

Pterophyllum scalare Pinoy Ghost Angelfish The Pinoy angelfish phenotype or variety results from the combination of the dark/black and blue traits/mutations. The dark/black trait is dominant while the blue trait is recessive. The blue trait expresses basically on the crown, back and unpaired fins. The lower two thirds of the body basically has very minimal or no blue expression. This blue "color"is a domestic mutation which is different from the blue colors expressed in wild angelfish. The domestic blue and wild blue colors can combine and produce bluer angelfish. Although the Pinoy angelfish is the combination of the dark/black and blue traits, there will be variations in overall color due to the pressence of other colors, yellow, orange and red... The Ghost phenotype refers to the complete/incomplete loss of body stripes due the heterozygous stripeless/blushing mutation.
