Hydrogen

By Luka Lamoreaux

Atomic Structure

If You'll look at the picture to the left, you'll see a picture of the atomic structure of the hydrogen atom (H). The hydrogen atom has 1 proton, and 1 electron, because its atomic number is 1. It has 0 neutrons, because its atomic weight is 1, or 1 proton.

Properties

Hydrogen is a nontoxic, nonmetallic, odorless, colorless gas, which melts at 13.99 K, and boils at 20.271 K. It has an average atomic weight of 1.0079 amu, making it the lightest element. Hydrogen is also the most abundant chemical substance in the universe.
Hydrogen has 1 ring, because it is in period 1, and has 1 valence electron, because it is in group one. It is a very reactive element, with similar properties to Lithium, Sodium, and other elements in group 1.
Hydrogen is included in the chemical formula for water, H2O. In water, there are two hydrogen atoms, and one Oxygen atom.
