The first IE of magnesium is greater than that of aluminium because
a) Al atom is very large when compared to Mg
b) Al atom has an electron more when compared to Mg
c) Mg has a stable electronic configuration
d) Al has a stable electronic configuration

Answered by GeN21

Answer:

c)Mg has stable electronic configuration.

Explanation:

Since Aluminum has the configuration

1s2,2s2,2p6,3s2,3p1 and Magnesium has configuration 1s2,2s2,2p6,3s2 . It is easy to see that aluminum will have low 1st IE because it wants to lose 1 electron to gain stable configuration. Mg will have higher IE because it needs more energy to become instable from stable configuration.

Answer:C)Mg has a stable electronic configuration

Explination: Mg (Z = 12) 1s2 2s2 2p6 3s2 . Al (Z = 13) 1s2 2s2 2p6 3s2 3p1 . Although the nuclear charge of aluminium is greater than that of magnesium, I.E of Mg is greater than that of Al. It is because Mg atom has more stable configuration than Al atom. IE1 of Mg >
