Manganese has 2 (two) electron that would free floating and able to form a metallic bond.
The electronic configuration of manganese is (Ar) 3d5 4s2. The two electron in 4s orbital are the valence electron which can freely move from one place to another.
This is a question that would have literally have taken two seconds to look up on google but the answer is 1.88 years.
I believe it goes as the following::
