Answer:
ml =0
Explanation:
The third quantum number of a 3s2 electron in phosphorus, 1s2 2s2 2p6 3s2 3p3 is ml=0.
The third quantum number of an [tex]3s^{2}[/tex] electron in phosphorus,
[tex]1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{3}[/tex] will be m = 0.
Quantum numbers were also the series of data which used to express the location as well as the energy of an atom or ion.
Phosphorus is the kind of element which atomic number will be 15. and can be represented by P.
Calculation of quantum number.
The electronic configuration of P(phosphorous) is [tex]1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{3}[/tex] .
It can be seen that 3s has only 2 electrons, hence, magnetic quantum number will be 0.
Therefore, the correct answer will be option (c).
