(a)
Interpretation: For the given
Concept Introduction:
- Pauli Exclusion Principle: No two electrons having the same spin can occupy the same orbital. To occupy the same orbital, two electrons must have opposite spins.
- Hund’s rule: When electrons occupy orbital, one electron enters each orbital until all the orbitals contain one electron. When the orbitals are singly filled, all the electrons have same spin where as in the doubly filled orbitals, electrons have opposite spin.
- Aufbau’s Principle: The electrons in an atom fill the lowest energy levels in order of increasing energy. The order in which the electrons should be filled is 1s,2s,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s,5f,6d.
- The maximum number of electrons that can be placed in a subshell is given by 2(2l+1). This gives 2,6,10 and 14 electrons for the sub shells of s, p, d, f respectively.
