What is the chemical formula for the compound magnesium perchlorate? Use the list of polyatomic ions and the periodic table to h
8_murik_8 [283]

The chemical formula for the compound magnesium perchlorate is Mg(ClO₄)₂

Magnesium perchlorate or Mg(ClO₄)₂ is an ionic compound.

Perchlorate here is an anion which is represented by ClO₄⁻. Perchlorate is a polyatiomic anion, where one Cl atom is bonded to four O atoms.

The magnesium cation is represented by Mg²⁺

So one Mg²⁺ cation combines with two ClO₄⁻ anion to form one molecule of Mg(ClO₄)₂
