|MATTER||Everything that has mass and takes up space.|
|ELEMENT||Substance made of only 1 kind of atom.|
|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
|ATOM||The basic building block of matter. Can’t be any
|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.|
|MIXTURE||Two or substances that mix together but each keeps its own identity.|
|SOLUTION||A mixture where substance spreads out evenly and will not settle.|
|SOLUTE||The substance being dissolved.|
|SOLVENT||What the substance is dissolved in.|
|SOLUBILITY||A way to measure how much a material dissolves into another.|
