Answer:

Neon (Ne) has an atomic number of 10, and sodium (Na) has an atomic number of 11. Neon has its outside shell full of electrons; therefore, it does not react with other elements. Sodium has 1 more proton and 1 more electron. That added electron is in the outside shell, making it a valence electron. It can fill that shell by losing the one electron which makes Na a very reactive element while Ne is not reactive.
