E. A direct measure of internal kinetic energy
Lithium, Sodium, Potassium; any of the Alkali Metals, which are farthest left on the periodic table. This is because they only have one electron in their outermost shell, so they would rather lose an electron rather than try to gain 7 to achieve that full outer shell.
Element name: Neon
element symbol: Ne
atomic number: 10
atomic mass: 20.1797
number of protons: 10
number of neutrons: 10
number of electrons: 2,8
interesting fact: the name means new, and it is pulled out of the air.
for the rest just add a neon bohr model ig
100.08 is the molecular mass.
