Question

How reactive is an atom of Sodium(Na) and why?

Sodium (Na) is not very reactive because it does not have a full valence shell.


Sodium (Na) is not very reactive because it can only bond with Chlorine (Cl) to become salt.


Sodium (Na) is very reactive because it does not have a full valence shell.


Sodium (Na) is very reactive because it does not have enough protons in the nucleus.

Answer 1

Sodium is very active with the Halogen family, having one valence electron it requires 7 additional electrons from another source to become a satisfied compound. So the answer would likely be the third answer choice,Sodium (Na) is very reactive because it does not have a full valence shell.
