Question

Paramagnetic species among the following
1.Na+
2.Mg2+
3.F-
4.P
​

Answer 1

Answer:

Na+ and Mg2+

Explanation:

Hope you find this helpfull

Answer 2

answer;

Phosphorus

Explanation:

paramagnetic species have 1 or more unpaired electrons while diamagnetic contains 0 unpaired electron. Here except phosphorus the other three ions are paired by loosing and gaining electrons.

Na+ = 2,8 remove 1e-

Mg2+= 2,8 remove 2e-

F- = 2,8 accept 1e-

P = 2,8,5

In phosphorus there exist an unpaired election in its outermost orbital. (3s², 3p³)
