Matter | Everything that has mass and takes up space |
Element | The ingredient that make up all other substances. Can't be broken down into other. |
Metals | Good conductors of electricity and heat. Can bend without breaking. Most have a gray. |
Nonmetals | Do not conduct heat / electricity very well. May be gas or solid. |
Semimetals | Sometimes like metals and sometimes like nonmetals. |
Atom | The smallest part of an element that still acts like a element. |
Atomic Arrangement | States that everything is made of atoms. |
Compound | A type of matter made of two or more elements. |
molecule | smallest particle of a compound that still acts like compound. |

Neutron | No charge. Found in the nucleus. |
Electron | Negative charge. Orbits the nucleus. |
Solid | Has a definite shape and volume. Particles are very close together and don't move past each other. keeps shape |
Liquid | Definite volume but not shape particles can move past each other takes shape of volume |
Gas | No definite shape or volume.Particles spread out evenly and take shape of container. Can be squeezed into smaller volume |
Plasma | Like a gas but conducts electricity like a metal occurs with high temps or electric charge. |
Melting Point | When solid to liquid or liquid solid. Sane temp as freezing point. |
Evaporation | When liquids become a gas. |
Condensation | When gas become a liquid. Gas particles touch cold surface and the temperature drops. |
