Matter
- Composed of tiny particles (atoms, molecules, ions) with fixed sizes.
- An atom uniquely defines a chemical element, consisting of a central nucleus (protons and neutrons) surrounded by electrons.
Molecules and Ions
- Molecules: Groups of atoms bonded together, the smallest unit that can partake in a chemical reaction.
- Ions: Atoms or molecules with an electric charge, formed when electrons are lost or gained.
States of Matter
- Plasma: An ionized gas with indefinite shape and volume, containing charged particles.
- Mass: The quantity of matter in an object.
- Volume: The space an object occupies, described using terms such as big, little, long, or short.
- Solid: Particles tightly packed in fixed positions, resulting in definite shape and volume.
Summary of the Five States of Matter
- Defined by distinct particle arrangements and properties including solids, liquids, gases, and plasma, each displaying unique characteristics regarding shape and volume.
