To indicate the oxidation number using Roman numerals.
e.g.
Ferric oxide or ferrous oxide /??? Which
Ferric oxide (Fe(II)O).
Ferrous oxide (Fe2(III)O3).
or
Potassium permasnganate KMnO4 The manganese is (+7) . hence
KMn(VII)O4
If the transition metal has more than one ion, you write the charge as a Roman numeral. For example copper can have an ion with a charge of 1+ and an ion with a charge of 2+. If they were combined with oxygen, they would be named copper (I) oxide and copper (II) oxide respectively.
When the compound contains at least two polyatomic ions of the same formula.
The chemical formula of an ionic compound that contains aluminium and chlorine is aluminium chloride - AlCl3.

Typically in writing an ionic compound, the cation is written first, then the anion.
Gold is a transition metal and sulfur is a nonmetal so the only bond here could be ionic.
When the compound contains at least two polyatomic ions of the same formula.
Water contains no ionic bonds as it is a covalent compound.
The chemical formula of an ionic compound that contains aluminium and chlorine is aluminium chloride - AlCl3.
It contains two different elements so yes, it is binary.

Typically in writing an ionic compound, the cation is written first, then the anion.
This is gallium(I) SULFIDE. It is a type II binary ionic compound meaning it contains transition metal and non-metal ions.
"Ternary" means that the compound contains three elements.
Gold is a transition metal and sulfur is a nonmetal so the only bond here could be ionic.
Because ionic compounds contain a metal while the covalent compound contains only non-metals.
