From each set, choose the element with highest ionization enthalpy and explain your answer.
B,Al,Ga

Text Solution

Verified by Experts

The element B has the highest ionisation enthalpy because in general the value decreases down the group. All these elements belong to group 13 in the order B, Al, Ga. Therefore, the first element B is expected to have the largest value.
