ILL MARK AS BRAINLIEST:) Tell me with your own words;

How to write a formula of an ionic and covalent compound.
*Include metals with more than one charge.
*Include polyatomic ions.

Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons.

A cation is a positively charged ion

An anion is a negatively charged ion.

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral.

Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other. Since hydrogen is a nonmetal, binary compounds containing hydrogen are also usually covalent compounds.

Metal + Nonmetal —> ionic compound (usually)

Metal + Polyatomic ion —> ionic compound (usually)

Nonmetal + Nonmetal —> covalent compound (usually)

Hydrogen + Nonmetal —> covalent compound (usually)
