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 the 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! |
|
|
Dentsity |
A measurement of how solid something is, specifically it is the mass per volume of a substance. (d=m/v)
|
|
|
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 on the outside of the nucleus. |
|
|
Periodic Table |
A chart that contains all the known elements; 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. |
|
|
Gas |
The state in which matter expands to occupy whatever volume is available. |
|
|
Physical Property |
Characteristic that you can see through direct observation that includes color texture,density,odor,luster,and state (solid,liquid,or gas) |
|
|
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 addition of energy. |
|
|
Evaporation |
The change of a substance from a liquid to a gas. |
|
|
Boiling |
The conversation of a liquid to a vapor. |
|
|
Freezing |
The change of 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 to a gas. |
