Explanation:
a) 1s²2s³2p⁵
As 2s orbital has 3 electron, it disobey Pauli's Excusion Principle. Accorfing to Pauli's Excusion Principle, an orbital can have maximum of two electrons which have opposite spins.
b) 1s²2s²2p⁴3s²
As 3s orbital which has higher energy is completely filled before complete feeling of 2p orbitals which are lower in energy, n + l rule is disobeyed in this configuration.
c) 1s²2s²2p₁²2p₂¹
In this configuration, 2 electrons are filled in 2p₁ while 2p₃ is empty. This minimizes number of unpair electrons. So, it disobeys Hund's rule of maxumum multiplicity.
