Matter

Matter

Matter is anything that occupies space and has mass. Made up of tiny building blocks called atom. (Space/Mass).

Non-Matter

non matter does not occupy space but has mass. It had a dual nature: wave and particle. (Energy, light, heat, sound, gravity, magnetic field, time)

Atom

Building blocks of all matter. Expressed in Angstrom 10^-10 meters. 99% of the mass of an atom is concentrated in the nucleus of an atom.

Ions

Ions are charged particles because of the addition or lost of electron in an atom.

  • Cation - when an ion lost electron and has a positive charge

  • Anion - when an ion gain an electron and has a negative charge

    • Monatomic ion - charged atom either cation or anion

    • Polytomic ion - group of elements bonded together that carries a charge

Monatomic Atoms

Atoms that can exist independently like the noble gasses.

Molecules

Group of two or more atoms bonded together chemically

  • Diatomic molecule - two bonded atoms

  • Polytomic molecule - three or more bonded atoms
