The first and second ionization energies of two elements from the 3rd row of the periodic table are given below.

Element A: 738 kJ/mol and 1451 kJ/mol

Element B: 496 kJ/mol and 4562 kJ/mol

What is element B?

Expert Solution

second ionisation energy of element B is much higher tha first ionisation energy
so, B after lossing one electron attain nobel gas configuration
also, given element is from third row
so, it must be Na

Answer : Na
