Hydrogen is the chemical element with the element symbol H and atomic number 1. It's essential for all life and abundant in the universe, so it's one element you should get to know better. Here are basic facts about the first element in the periodic table, hydrogen. Fast Facts: Hydrogen...
First element in the periodic table. In normal conditions it’s a colourless, odourless and insipid gas, formed by diatomic molecules, H2. The hydrogen atom, symbol H, is formed by a nucleus with one unit of positive charge and one electron. Its atomic number is 1 and its atomic weight...
In this sense, Thomson’s “inescapable”Footnote 15 hypothesis of the electron works as the symbol of the opening of a period when the concept of particle fully develops its usefulness for research into the entire foundations of physics. The previous sections also sketched a very diverse and ...
The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also known as atomic weight (symbol: Ar). Notes (H) m: Standard Atomic Weight H: [1.00784,1.00811] Isotopic Composition199.99%199.99%20.01%20.01%...
a very hard almost colourless crystalline metalloid element that in impure form exists as a brown amorphous powder. It occurs principally in borax and is used in hardening steel. The naturally occurring isotopeboron-10is used in nuclear control rods and neutron detection instruments. Symbol: B; ...
