Why are s-block metals typically more reactive than p-block metals?

Since s-block metals have lower ionization energies, they’re more likely to give away their electrons which makes them more reactive

To elaborate, the lower ionization energy is partially because the valence electrons are further from the nucleus, meaning the attraction is less.

S blocks are usually more reactive due to the fact that they have lower ionization energies, and because of this, they are able to give away electrons easily. These are more likely to make a reaction, and for noble gas electron configuration, elements only need to lose 1 or 2 electrons in their s-block.

On the other hand, p-blocks are less reactive because they have higher ionization energies that have mostly non-metals. They have fuller shells that make it harder for them to give away electrons. They need to give away more electrons, making them less likely to make a reaction.
