Question

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

Question 1 options:


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

3rd one:
it is very reactive because it does not have a full Valence shell.

this is because it's in group 1 so it has one electron in its outer shell, and it wants to have a full outer shell ( which it can gain by losing the electron in a reaction).

Hope this helps :)
