Can you help me with Periodic Trends?

Question

#IE_1#:896 kJ/mol
#IE_2#:1752 kJ/mol
#IE_3#:14,807 kJ/mol
#IE_4#:17,948 kJ/mol
1. It is often said that all of chemistry is governed by electrostatic interactions. What do you
think holds the electrons of Mg to its nucleus?
2. Why do you think the ionization energy for Mg increases as you go from# I_1# to #I_4#?
3. Why do you think there is such a large difference between the 2nd and 3rd ionization energies of Mg?

See below

the #+# charge of the nucleus The distance between electrons and the nucleus decreases and inner electron shielding decreases as electron lost effective nuclear charge increases. A large increase in I.E. suggests a major shell change, in this case from the third to the second shell. Distance [from nucleus], shielding [number of inner electrons], and charge [on nucleus, i.e. excess protons over electrons] are the main factors influencing IE.
