3.1H Ionization Energies of the Transition Metals

I keep missing school :(

What did Structure 1.3 tell us about Ionization Energy?

Ionization energy is a measure of the energy needed to pull an electron away from the nucleus of an atom/ion

What determines how easily the electron can be pulled away from a nucleus?

The attraction between the nucleus and that electron

(Large IE = large attraction between electron and nucleus)

Why do transition metlas have variable oxidation states?

their successive ionization energies are close in value

What does the ionization energy of a normal metal look like?
