(the greater the electroneg. the greater the attraction is for bonding e-

Question 2

Ionization Energy

Answer 2

the energy required to remove an election
Mg –> Mg+
Mg+ –> Mg2+

Question 3

Electron Affinity

Answer 3

the energy change that occurs when an electron is added to a gaseous atom.
the “ease” at which an atom will accept an e-
the greater the attractive pull of nucleus = the greater the electron affinity
