Mn, because it can lose 7 electrons to get an oxidation state of +7.

It is Mn. It can become +7

Mn belongs to the d-block of the periodic table and has the [Ar] 3d5 4s2 electron configuration. To become the noble gas state (Ar) it has to give off 7 electons.
E.g. V [Ar] 3d3 4s2 has to give off 5 electrons.

+6 in MoO3 and MoF6 I went to the "practise manual of Chemistry & Physics" and located that there are molybdenum hexafluoride and trioxide. i became into truly fascinated in fluorides, because of the fact they many times tutor any surprisingly severe oxidation states of the climate.
