ELEMENT |
Basic building block of matter;cannot be broken down to a simpler substances,consists of atoms of only one type. |
|
ATOM |
The smallest particle of an element that has the chemical properties of that element.These are building blocks of matter. |
|
MASS |
The amount of matter in a substance.You can measure mass using a balance.This is not to be confused with weight. |
|
DENSITY |
A measurement of how solid something is, specifically it is the mass per unit volume of a substance. |
|
VOLUME |
The amount of space an object takes up. |
|
MATTER |
Anything that has mass and takes up space (has volume) |
|
NUCLEUS |
The center of the atom that contains both protons and neutrons |
|
PROTONS |
The positively charged particles of an atom;found in the nucleus. |
|
NEUTRONS |
The small particle of an atom that carries a neutral charge;found in the nucleus |
|
ELECTRONS |
The negatively charged particles of an atom;found outside the nucleus |
|
PERIODIC TABLE |
A chart that contains all the known element;arranged by the atomic number |
|
SOLID |
The state in which matter maintains a fixed volume and shape |
|
LIQUID |
The state in which matter maintains a fixed volume but adapts to the shape of its container |
|
PHYSICAL PROPERTY |
Characteristic that you can see through direct observation that includes color,texture,density,odor,luster,and the state (solid,liquid,or gas) |
|
GAS |
The state in which matter expands to occupy whatever volume is available |
|
CHEMICAL PROPERTY |
Properties that can only be observed when one substance changes into a different substance |
|
PHYSICAL CHANGE |
A change from one state (solid or liquid or gas) to another without a change in chemical composition |
|
CHEMICAL CHANGE |
Results in the formation of one or more new substances; a change that cannot be reversed |
|
MELTING |
Change of state from a solid to a liquid with the addition of energy |
|
EVAPORATION |
The change of a substance from a liquid to a gas |
|
BOILING |
The conversion of a liquid to a vapor |
|
FREEZING |
The change of a state from a liquid to a solid |
|
CONDENSATION |
The change of state from gas to a liquid |
|
SUBLIMATION |
The process in which a solid changes directly into a gas |
