Sequential removal of electrons was done in Y and energy required measured as follows.

a) In which group is element Y. Explain.
b) Element Z is next to Y and to its left in the same period. Which one between Z and Y has a bigger 1st ionisation energy.
Explain.

Answers

a) Group II
Reason : after the loss of the 2nd electron excess energy is require to remove an electron from the stable ion formed
b) Y
Reason : Because it has a smaller atomic radius than Z hence stronger effective nuclear charge
