40 points how do you determine the chemical reactivity for metals by using the periodic table?

The idea is that the reactivity of metals increases as you move down the group. This is due to weaker electrostatic forces of attraction between the positive nucleus and the negative outer shell electron.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
