Explain the energy transfers when ionic bond are made, include ionization energy and electron affinity.

In ionic bonds, the metal is donor of electrons (loses electrons) and become a positively charged ion (cation) and nonmetal is acceptor of electrons (accepts those electrons) and become a negatively charged ion (anion). 
Ionization energy of the metal (easy to remove valence electrons) is lower than nonmetal and  electron affinity of the nonmetal is higher than metal.

No. an alpha particle is a pair of protons and a pair of neutrons, i.e. a helium
