Question

How many unpaired electrons are present in Mn2+ ion? How does it influence magnetic behaviour of Mn2+ ions?

Answer 1

Mn2+=[Ar]4s0 3d5

Mn2+ has 5 unpaired electrons  

Manganese 2+ is paramagnetic.

Explanation:

An unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair.

Each atomic orbital of an atom (specified by the three quantum numbers n, l and m) has a capacity to contain a maximum of two electrons with opposite spins, an electron pair.

Answer 2

Answer:5

Explanation:it has atomic number 25

I.e 1s2 2s2 2p6 3s2 3p6 3d5 total 23 because it already lost 2 electrons mn2+=23 electrons
