"For a given atom, one electron ONLY......"

Explanation:

A given electron is defined by FOUR quantum numbers...n_"principle quantum number", l_"azimuthal quantum number", m_(l("magnetic quantum number")), and m_(s("spin quantum number")). The Pauli exclusion principle states that NO TWO electrons can have the same set of FOUR quantum numbers: electrons in the same orbital are differentiated by m_s=+-1/2....
