What are hydrogen atoms?

Some articles on hydrogen, hydrogen atoms, hydrogens, atom, atoms:

Dihydrogen Bond
... In chemistry, a dihydrogen bond is a kind of hydrogen bond, an interaction between a metal hydride bond and an OH or NH group or other proton donor ... With a van der Waals radius of 1.2 Å, hydrogen atoms do not usually approach other hydrogen atoms closer than 2.4 Å ... In this molecule, like the one studied by Brown and Hazeltine, the hydrogen atoms on nitrogen have a partial positive charge, denoted Hδ+, and the hydrogen atoms on boron have a partial ...
Hexyne - Properties - Spectral Characteristics
... The less deshielded triplet corresponds to the terminal methyl hydrogen atoms that experience spin-spin splitting from the adjacent methylene hydrogen atoms ... The quartet corresponds to the more deshielded methylene hydrogen atoms that are spin-spin split by the adjacent methyl hydrogen atoms ... The methylene hydrogens don't form a complex multiplet because the internal alkyne function that is adjacent to them does not contain any bonded hydrogen atoms with which they can interact ...
Technetium Compounds - Characteristics - Chemical Properties - Hydride and Oxides
... The reaction of technetium with hydrogen produces the negatively charged hydride TcH2− 9 ion, which has the same type of crystal structure as (is ... It consists of a trigonal prism with a technetium atom in the center and six hydrogen atoms at the corners ... Three more hydrogen atoms make a triangle lying parallel to the base and crossing the prism in its center ...
Molecular Structure Diagram - Skeletal Formulas
... chemist Friedrich August Kekulé von Stradonitz the carbon atoms in this type of diagram are implied to be located at the vertices (corners) and termini of line segments ... Hydrogen atoms attached to carbon atoms are not indicated each carbon atom is understood to be associated with enough hydrogen atoms to give the carbon atom four bonds ... of a positive or negative charge at a carbon atom takes the place of one of the implied hydrogen atoms ...
Animal Nutrition - Fat
... fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol ... Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer ...

Famous quotes containing the words atoms and/or hydrogen:

    Scatter my ashes, strew them in the air:
    Lord since thou know’st where all these atoms are,
    I’m hopeful thou’lt recover once my dust,
    And confident thou’lt raise me with the just.
    —James Graham Marquess of Montrose (1612–1650)

    All you of Earth are idiots!... First was your firecracker, a harmless explosive. Then your hand grenade. They begin to kill your own people a few at a time. Then the bomb. Then a larger bomb, many people are killed at one time. Then your scientists stumbled upon the atom bomb—split the atom. Then the hydrogen bomb, where you actually explode the air itself.
    Edward D. Wood, Jr. (1922–1978)
