Elements |
Basic building block of matter; cannot be broken down to a simpler substances, consists of atoms of only 1 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 by using a balance.This is not to be confused withe 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 can take up. |
|
|
Matter |
Anything that 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 an atom |
|
|
Nuetrons |
The small particle of an atom that carries a natural charge; found in the nucleus |
|
|
Electrons |

|
|
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
|
The character its that you can see through direct observation that includes color texture, density,odor,luster, and state ( solid, liquid, or gas).
|
|
|
Chemical Property
|
The properties that can only be observed when one substance changes into a different substanc
|
|
|
Physical Change
|
A change from one state ( solid or liquid or gas)to another without a change in chemical composition
|
|
|
Chemical Change |
The results in the formation of one or more new substances; A change that cannot be reversed
|
|
|
Melting |
Change of state from solid to liquid with the addition of energy |
|
|
Evaporation |
The change of a substance from a liquid to a gas
|
|
|
Boiling |
The conversion of state from 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 into a gas
