The correct set of quantum number for the unpaired electron of chlorine atom is
`{:(n,l,m_(1)):}` " " `{:(n,l,m_(1)):}`

Options

A. ` {:(n,l,m_l,,),(2,1,0,,):}`
B. ` {:(n,l,m_l,,),(2,1,1,,):}`
C. ` {:(n,l,m_l,,),(3,1,1,,):}`
D. ` {:(n,l,m_l,,),(3,0,0,,):}`

Answer

C

Explanation

( c) Electric configuration of chlorine is `[Ne] 3s^2, 3 p^5`
`:.` Unpaired electron is found in `3 p` sub-shell.
`:. n = 3, 1 = 1, m = 1`.
