Helium Sam mendenhall

This is a Bohr model of the atom helium. The '0's represent neutrons, the '+'s represent protons, and the '-'s represent electrons.
Some chemical properties of Helium include that it has a boiling point of -452*F, it is less dense that oxygen, and has a low reactivity. Some physical properties include it is colorless, tasteless, and odorless.

Helium is at the top right corner of the periodic table in group 18, which means it's not reactive due to its full valence shell. It is in the first period, meaning that it only has one energy shell.

Because Helium is a noble gas, this means that it does not react with anything because of its full valence energy shell.

Helium is lighter than air, it can take you anywhere.
