Which of the two elements would be more reactive, element A of atomic number 36 or element B of atomic number 19 ?

Text Solution

Verified by Experts

The electronic configurations of elements A and B are given below.
`{:(A(36),2,8,18,8),(B(19),2,8,8,1):}`
Since the outermost shell of element A is completely filled, it is stable and unreactive . The outermost shell of element B contains one electron only . Hence , it is more reactive.
