Which of the following electronic configurations has maximum energy?Which of the following electronic configurations has maximum energy?Which of the following electronic configurations has maximum energy?Which of the following electronic configurations has maximum energy?Which of the following electronic configurations has maximum energy?

Options

  1. AIf ( ^ 20 C_ r = ^ 20 C_ r-10 ) then ( ^ 18 C_ r ) is equal to
  2. BIf ( ^ 20 C_ r = ^ 20 C_ r-10 ) then ( ^ 18 C_ r ) is equal to
  3. CIf ( ^ 20 C_ r = ^ 20 C_ r-10 ) then ( ^ 18 C_ r ) is equal to
  4. DIf ( ^ 20 C_ r = ^ 20 C_ r-10 ) then ( ^ 18 C_ r ) is equal to

Correct answer

A. If ( ^ 20 C_ r = ^ 20 C_ r-10 ) then ( ^ 18 C_ r ) is equal to

Step-by-step solution

The order of increasing energy of the sub-atomic orbitals is s<p<d<fs < p < d < f. The energy in excited state is more than that in the ground state. In option (a), two electrons are in excited state therefore, it has maximum energy.
