Manganese (II) Phosphate

Explanation:

Mn3(PO4)2 is the compound given in this question. Manganese is the metal and hence it will come first in the name. Along with the name of metal it is essential to determine the valency of the metals based on the compound structure.

Here 2 PO4 attaches with 3 Mn

Valence of PO4 is -3

So the total electrons contributed by PO4 is 3*2 = 6

Now Mn has 3 atoms in the compound. Thus, per atom the valency must be 2 in order to satisfy -6 charge of PO4

Thus, valency of Mn is 2

So, the name will be

Manganese (II) Phosphate.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
