Question

If a metal has 2 valence electrons is it stable?​

Answer 1

Answer:

Helium (He) is similar in that it, too, only has room for two electrons in its only valence shell. Hydrogen and helium have only one electron shell. The first shell has only one s orbital and no p orbital, so it holds only two electrons. Therefore, these elements are most stable when they have two electrons.

Answer 2

Answer:

It is “eager” to give up this electron in order to have a full outer energy level, because this will give it the most stable arrangement of electrons. You can see how this happens in the Figure below. Group 2 elements with two valence electrons are almost as reactive as elements in group 1 for the same reason
