Question

what is the value of the magnetic quantum number (ml) for an electron in the 3p orbital?

Explanation:

Step1: Recall the rules for magnetic quantum number

For a given orbital type, the magnetic quantum number \(m_l\) can take values from \(-l\) to \(+l\) where \(l\) is the azimuthal quantum number. For a \(p\) orbital, \(l = 1\).

Step2: Determine possible \(m_l\) values

When \(l=1\), \(m_l=- 1,0, + 1\)

Answer:

\(-1,0,1\)
