Question

consider the following set of quantum numbers: ( n = 2 ), ( l = 1 ), ( m_l=-1 ), and ( m_s = 0 ). this is not a possible set of quantum numbers for an electron in an atom. choose the incorrect quantum number. answer: a ( n = 2 ) b ( l = 1 ) c ( m_l=-1 ) d ( m_s = 0 )

Explanation:

The spin quantum number \(m_s\) can only have values of \(+\frac{1}{2}\) or \(-\frac{1}{2}\). A value of \(m_s = 0\) is not allowed for an electron's spin quantum number.

Answer:

D. \(m_s = 0\)
