Sc(OH)3 is a polyatomic ionic covalent compound because it consists of a metal (Scandium) bonded to a polyatomic ion (hydroxide, OH). The hydroxide ion is a covalent unit made up of one oxygen and one hydrogen atom but acts as a single unit in this compound.
CaSO4 is a polyatomic ionic compound. It consists of a metal cation (Ca2+) and a polyatomic anion (SO42-) that are attracted to each other through ionic bonds.
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
Na2Cr2O7 is an ionic compound with a polyatomic ion. The polyatomic ion present in this compound is the chromate ion (Cr2O7)^2-.
Na2O is ionic and consists of Na+ and O2- ions.
Polyatomic ions are named with their specific names, regardless of their overall charge. When naming an ionic compound with a polyatomic ion, the name of the cation is written first followed by the name of the anion (polyatomic ion).

An ionic compound with polyatomic ions is formed through the attraction between positively charged metal ions and negatively charged polyatomic ions. Polyatomic ions are covalently bonded groups of atoms that have an overall charge, making them act as a single charged unit in the formation of ionic compounds.
If the compound contains a polyatomic ion, simply name the ion.
Polyatomic ions can have both ionic and covalent bonds. Ionic bonds are formed between the positively and negatively charged ions within the polyatomic ion, while covalent bonds are formed by sharing electrons between the atoms within the polyatomic ion.
MgCO3 is a compound made up of an ionic bond between magnesium (Mg) and the polyatomic ion carbonate (CO3). The carbonate ion has covalent bonds within it, but overall the compound is considered to have ionic bonding due to the transfer of electrons between magnesium and carbonate.
Magnesium acetate (MgC2H3O2) is ionic. Magnesium is a metal, and acetate is a polyatomic ion consisting of carbon, hydrogen, and oxygen. Ionic compounds form between metals and nonmetals or polyatomic ions.
LiC2H3O2 is an ionic compound. It contains lithium (Li) which is a metal, and acetate (C2H3O2) which is a polyatomic ion with a negative charge. Ionic compounds are formed by the transfer of electrons between a metal and a non-metal or polyatomic ion.
Aluminium is a chemical element, metal and form ionic bonds.
