Answer:

#"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#....
