Quantum number checker

Validate n, l, m_l, m_s and relate to subshell capacity.

Calculator

Model / formula

Check n, l, m_l, m_s (use m_s = ±0.5)

l (0=s, 1=p, 2=d, 3=f)

m_l

m_s (+0.5 or −0.5)

Result

Valid set for subshell 2p (capacity 6 e⁻). n=2, l=1, m_l=0, m_s=+½

Use m_s = ±0.5 in the form. Relates to subshell s, p, d, f.
