Answer 1

Answer:

please follow me

Explanation:

If you want it quick, the answer is before the long list of what element M is.

Well, Oxygen has a charge of 2-. If you have 3 atoms with a charge of 2-, you have a charge of 6-, 3 multiplied by 2-. That means that the 2 atoms of M together have a charge of 6+ to cancel out the 6-, meaning M has a charge of 3+, 6+ / 2.

Phosphate, or PO4, has a charge of 3-. This will directly cancel out the 3+ of M, meaning a 1:1 ratio.

The answer is MPO4.

As a side note, according to my PERIODIC TABLE OF IONS, M could be one of Aluminum, Scandium, Titanium, Vanadium, Chromium, Iron, Cobalt, Nickel, Gallium, Yttrium, Niobium, Ruthenium, Rhodium, Indium, Antimony, Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium, Gold, Thallium, Bismuth, Actinium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium, or Lawrencium.
