Ionic Bond

A bond that forms between metals and non-metals, characterized by the transfer of electrons.

Naming Ionic Compounds

The metal is named first, followed by the non-metal, with the non-metal's ending changed to "ide."

Subscripts in Ionic Compounds

Small numbers used to indicate the number of atoms of each type in the compound.

Properties of Ionic Compounds

They dissolve easily in water and polar solvents, separate easily, and typically have high melting temperatures.

Covalent Bonding

A bond formed between two non-metals where electrons are shared.

Single Bond

A covalent bond involving the sharing of two electrons.

Double Bond

A covalent bond involving the sharing of four electrons.

Physical Change

A change that alters the state of matter without changing its chemical composition.

Chemical Change

A process that results in a chemical reaction, altering the substance's chemical composition.

Atom

The basic unit of matter, consisting of a nucleus surrounded by electrons.

Compound

A substance formed from two or more different elements that are chemically joined.

Mixture
