Please help me fast!! Which element is chemically active in between Sodium and Neon?

Element is chemically active in between Sodium and Neon is explained below in details.

Explanation:

Electrons revolve the electron in "cases" (power levels), and only a specific quantity of electrons can survive in each case. ... For example, Sodium has one valence electron, Neon has eight valence electrons, and Chlorine has seven valence electrons. The quantity of valence electrons an atom has concluded its reactivity.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
