Term | Definition |
Matter | makes up everything |
elements | there are over 100 of these things and they make up most things |
semimetals | it reacts like metals sometimes but is not one |
atoms | the smallest part of a element that still has the properties is a |
GAS | No definite volume or shape. Particles spread out evenly and take
shape of container. Can be squeezed into a smaller volume |
compound | a is a type of matter made of two or more elements |
molecule | the smallest part of a compounds that still has the properties is called a |
nonmetals | does not react like metals |
metals | good conductors of electricity and heat and it cand bend |
atomic theory | states everything is made of atoms |
molecule | smallest part of a compound that still is one |
proton | positive charge found in the nucleus |
nuetron | no charge found in nucleus |
electron | negative charge orbits 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 |
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 |
