This is radon, it has a full outer shell of electrons, so it is technically non reactive
Calcium
Neon is already a stable element with a full outer electron shell, so it does not need to gain any electrons to achieve stability. Neon has 10 electrons in total, with a full valence shell of 8 electrons. Therefore, it is already in a stable configuration.
Two electrons from each element are shared; the total is four electrons.
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Calcium
Phosphorous
This element is xenon.

This element is xenon.
ARGON has 18 electrons, with an atomic number of 18 and an Atomic Mass of 40. It has 22 neutrons, is considered a Nobel gas, in that it is inert under most conditions, and is colorless.

Boron has 3 valence electrons out of five total electrons.
The velence electron will vary for element to element and can have 1 to 8 valence electrons.
Neon is not reactive at all because it has a full p sublevel of electrons (8 valence electrons total). This is a very stable configuration, and as a result, neon is neither a reactant nor a product in normal chemical reactions.
