A.) Phosphate ion or Orthophosphate
d.) Hydroxide
D.) Ammonium

C.) Nitrate
f.) Sulfur dioxide
Metals generally form cations, meaning they become positively charge - this positive charge is due to the loss of electrons.
Answer:
The answer to your question is: letter b Sulphur
Explanation:
Remember that in neutral molecules the sum of the oxidation numbers equals zero.
Mg⁺²S⁺⁶O⁻²₄
Magnesium = +2
Sulphur = +6
Oxygen = -2 x 4 = -8
Warmer atoms expand. There is also more movement. This is also explained when putting it into terms with solid vs. gas. in a solid, the atoms vibrate, but they can't move very far because there is not a lot of space between them. In a gas, on the other hand, the atoms are spread apart, and they move very fast. Putting it into context with water, the steam (gas) version is hot, and the ice cube (solid) version is cold.
