Question

The energy of an electron present in the first orbit of an atom is ____ than the energy of an electron in the other orbitals.

Answer 1

1. The electrons closest to the nucleus are found to have lower potential energy but possess high kinetic energy.
2. Since the total of these is the orbital energy, the overall electrons closest to the nucleus have the lowest orbital energy.

Therefore, the energy of an electron present in the first orbit of an atom is lower than the energy of an electron in the other orbitals.
