Question

select the quantum numbers associated with the 2p orbital. principal quantum number (n) angular momentum quantum number (l) possible magnetic quantum numbers (m_l)

Explanation:

Step1: Identify principal quantum number

The '2' in 2p indicates the principal quantum number $n = 2$.

Step2: Identify angular - momentum quantum number

For p - orbitals, the angular - momentum quantum number $l=1$.

Step3: Determine magnetic quantum numbers

The magnetic quantum number $m_l$ ranges from $-l$ to $+l$. When $l = 1$, $m_l=- 1,0,1$.

Answer:

Principal quantum number ($n$): 2
Angular momentum quantum number ($l$): 1
Possible magnetic quantum numbers ($m_l$): -1, 0, 1
