Chemical Composition can be classified as:

• substance and mixture

• pure mixture and substance

• pure and substance mixture

• pure substance and mixture

Solid, Liquid and Gas are:

• Pure Substance

• Chemical State

• Physical State

• Elements

Composed of only one (1) kind of atom and cannot be broken down into simpler pure substances by chemical means.

• Elementary

• Element

• Compound

• Complex-Compund

Composed of two kinds of atoms combined in definite proportion and can be broken down into two (2) or simpler pure substances by chemical means.

• Element

• Compound

• Mixture

• Matter

Physical combination between two or more pure substances, in varied proportions, in which each substance retains its own chemical identity.

• Pure Substance

• Element

• Compound

• Mixture

A mixture that contains visibly different phases or parts, each of which has different properties and are distributed non-uniformly.

• Heterogeneous Mixture

• Homogeneous Mixture

A mixture that contains only one visibly distinct phase, which has uniform properties throughout.

• Homogeneous Mixture

• Heterogeneous Mixture

A mixture of two or more metals.

• Iron

• Alloy

• Mercury

• Sodium

Its purest state, each molecule consists of two (2) thus the di-iodine atoms.

• Biatomic Molecule

• Diatomic Molecule

• Diatolic Molecule

• Monotomic Molecule
