Molecules compound formula threshold 3

Ionic Bond

A bond formed by the electrostatic attraction between positively charged cations and negatively charged anions.

Covalent Bond

A bond formed by the sharing of one or more pairs of electrons between atoms.

Cation

A positively charged ion formed when an atom loses one or more electrons.

Anion

A negatively charged ion formed when an atom gains one or more electrons.

Monatomic Ion

An ion formed from a single atom.

Polyatomic Ion

An ion composed of two or more atoms covalently bonded together that acts as a single charged entity.

Ionic Compound

A compound that consists of ions held together by ionic bonds, typically formed from a metal and a non-metal.

Hydrate

An ionic compound that contains water molecules as part of its crystalline structure.

Empirical Formula

A formula that represents the simplest whole-number ratio of the different atoms in a compound.

Molecular Formula

A formula that indicates the actual number of each type of atom in a molecule.

Naming Ionic Compounds

The name of the compound consists of the cation name followed by the anion name, with the anion name modified for monatomic ions.

Binary Acid

An acid that consists of hydrogen and one other nonmetal element.

Oxyacid

An acid that contains hydrogen, oxygen, and another element, typically derived from a polyatomic ion.

Nomenclature

A system of naming compounds in chemistry, including specific rules for different types of compounds.

Valency

The combining power of an element, often determined by the number of electrons it can lose, gain, or share.

Greek Prefixes

Prefix terms (like mono-, di-, tri-, etc.) used in naming to indicate the number of atoms in molecular compounds.

Electron Transfer

The movement of electrons from one atom to another, leading to the formation of ions.

Chemical Bonding

The joining of atoms to form new substances; involves attraction between atoms or ions.

Covalent Compounds

Compounds formed when nonmetals share electrons.

Transition Metals

Elements that may exhibit variable charges due to their ability to lose different numbers of electrons.
