Question

How reactive is an atom of Sodium(Na) and why? Question 1 options: 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. 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. Save

Answer 1

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

Answer 2

I'm pretty sure the answer is the first one. The fact that it doesn't have a full valence shell means that electrons from other atoms can react and bond with the sodium atom.
Hope this helps x
