ZnS is correct for Zinc Sulphide (I refuse to spell sulphur with an f) - Zn likes to form +2 ions losing the 2 4s electrons to form the +2 oxidation state, and S likes to either form -2 or +6 oxidation states, thus forming ZnS
The ionic compound ZnS is zinc sulfide.
Zinc sulfide
The formula for the ionic compound formed between zinc and sulfur is ZnS, which is known as zinc sulfide. In this compound, zinc has a 2+ charge (Zn2+) and sulfur has a 2- charge (S2-), so they combine in a 1:1 ratio to form a neutral compound.
ZnS is a covalent crystal. Although composed of positively charged zinc ions and negatively charged sulfur ions, the bonding within ZnS is primarily covalent due to the sharing of electron pairs between the zinc and sulfur atoms.

FeO is Iron(II)oxide, archaically , Ferrous oxide. Do NOT confuse with Fe2O3, which is Iron(III)oxide ; Archaically Ferric oxide. The 'iron' atom is in different oxidation states for these two compounds. NB 'Fe' is the chemical symbol for 'Iron', and comes from Latin 'Ferrum' for iron.
The name of the ionic compound Cu3PO3 is copper(I) phosphite.
Sodium bromite is the name of the ionic compound NaBrO2.
