There is a new electron shell added with each new row (period). So there electrons are further form the nucleus, which makes the atom larger.
Electrons are added in the same shell and are strongly attracted to the positive nucleus. The nucleus pulls electrons in very tightly, which makes the atom smaller.
Alkali metals on ly have 1 valence electron so it takes less energy to remove them because they are so far away from the nucleus….that is what make it easier to react!
