A period three element has 738, 1451, and 7733 kJ/mol as its first three ionization energies. What is the symbol of this element?

Solutions

Expert Solution

Period 3 Elements --> Na,Mg,Al,Si,P,S,Cl,Ar

The Given Ionisation Energies are:

IE1 IE2 IE3

738<----(713)--->1451<---(6282)--->7733 (Kj/mol)

(the numbers in the brackets are the difference between given consecutive values)

There is a big jump between IE2 and IE3 i.e, 2nd and 3rd Ionisation energies.

So, more energy is required to pull a 3rd electron from the shell

Hence,the element has 2 valence electrons.

So the 3rd period element is Magnesium (Mg)
