MATTER Everything that has mass and takes up space.
ELEMENT The ingredients that make up all other  substances.  Can't be broken down into other  substances.
METALS good conductors of electricity and heat.  Can bend  without breaking.  Most have a gray color
NONMETALS Do not conduct heat / electricity very well.  May  be a gas or a solid 
SEMI‐METALS  sometimes like metals and sometimes like  nonmetals
ATOM the smallest part of an element that still acts like  that element 
ATOMIC THEORY  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  that compound
PROTON Positive charge. Found in the nucleus
NEUTRON No charge. Found in the nucleus 
ELECTRON Negative charge. Orbits the nucleus
SOLID Has a definite volume or shape. Particles are very close together, and don’t move past each other.  Keeps its shape.  
LIQUID Has a definite volume but not shape. Particles can move past each  other. Takes shape of container
GAS No definite volume or shape. Particles spread out evenly and take  shape of container. Can be squeezed into a smaller volume
PLASMA Like a gas, but conducts electricity like a metal.  Occurs with high  temps or electric charge.
MELTING POINT Solid to liquid or liquid to solid.  Same temperature as freezing point.
EVAPORATION When liquids become a gas
CONDENSATION When gas becomes a liquid.  Gas particles touch a cold surface and  the temperature drops.
BOILING POINT The temperature at which evaporation occurs
