Element |
Basic building block of matter, cannot be broken down to a simpler substances. Consist of atoms of only one type |
|
Atom |
The smallest particle of an element that has the chemical properties of that element. Theses are the building block 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.(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 an atom that contains both protons and neutrons |
|
Protons |
The positively charged particles of an atom;found in the nucleus |
|
Electrons |
The negatively charged particles of an atom;found outside the nucleus |
|
Neutrons |
The small particle of an atom that carries a neutral charge; found in 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 it's container |
|
Gas |
The state in which matter expands to occupy whatever volume is available |
|
Physical Property |
Characteristic that you can see through directs observation that includes color texture,density,odor,luster,and state(solid,Liquid,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 move new substances; a change that cannot be reversed |
|
Melting |
Change of a state from 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 a state from gas to liquid |
|
Sublimation |
The process in which a solid changes directly into a gas. |
