Question

Solution

Correct option is

n = 2

for an atom of atomic number Z, the radius of the nth orbit is given by Where is a constant. For the ground state of hydrogen (Z = 1),n = 1 so that

r1 = K

let n be the energy state of Be+++ for which the orbital is r1. Putting Z = 4 and rn = r1 = K is eq. (i) we get .
