$1s^2 2s^2 2p^6 3s^2$ is the electronic configuration of the metal

The orientation of an atomic orbital is governed by

Write the increasing order of energy for $2p, 3p, 4p, 5p$ orbitals.

For the configuration shown in the image,which rule is violated $:-$

Identify which of the following sets of quantum numbers are not possible and explain why.
$(a) n = 0, l = 0, m_l = 0, m_s = +1/2$
$(b) n = 1, l = 0, m_l = 0, m_s = -1/2$
$(c) n = 1, l = 1, m_l = 0, m_s = +1/2$
$(d) n = 2, l = 1, m_l = 0, m_s = -1/2$
$(e) n = 3, l = 3, m_l = 3, m_s = +1/2$
$(f) n = 3, l = 1, m_l = 0, m_s = +1/2$
