increases

the energy required to add an electron to a specific atom

the energy required to shield the outer electrons from the nucleus

how much energy it takes to remove an electron from an atom

a measure of the ability of an atom to attract electrons

electrons are closer to the nucleus

their is a weak pull between electrons from the nucleus, making them easily moveable

feel more of a pull from nucleus, making them harder to move

electrons are further from the nucleus
