Yes, which is why elements with more or fewer valence electrons react with other elements.

No, each group number is different.

Answer 1

The correct response is:

Usually, but hydrogen and helium are exceptions.

This refers to the octet rule, which states that atoms tend to be most stable when they have eight valence electrons. However, hydrogen and helium are exceptions because hydrogen is stable with just 2 valence electrons (like in a helium configuration), and helium is already stable with its two valence electrons.
