Basic building blocks of matter, cannot be broken down a simpler substance consists of atoms of only one type |
Element |
|
The smallest particle of an element that has chemical properties of that element. These are the building blocks of matter. |
Atom |
|
The amount of matter in a substance. You can measure matter in a substance. You can measure matter in a substance. You can measure mass using a balance be confused with weight |
Mass |
|
A measure of how old something is, specifically is the mass per unit volume substance D=m/v |
Density |
|
The amount of space an object takes up |
Volume |
|
has mass and takes up space |
matter |
|
the center of an atom that contains both protons and neutrons |
Nucleus |
|
positively charged particles of an atom found in the nucleus |
protons |
|
neutrons |
the small particle of an atom that carries a neutral charge found in the nucleus |
|
the negatively charged particles of an atom found outside the nucleus |
electrons |
|
a chart that contains all the known elements arranged by the atomic number |
periodic table |
|
solid |
the state in which matter maintains a fixed volume and shape |
|
the state in which matter maintains a fixed volume but adapts to the shape of its container |
liquid |
|
the state in which matter expands to occupy whatever volume is available |
gas |
|
characteristic that you can see through direct observation that includes color texture density odor luster and state (solid liquid and gas) |
Physical Property |
|
properties that can only be observed when one substance changes into a different substance |
chemical property |
|
Physical Change |
a change from one state (solid or liquid or gas) to another without change in a chemical composition |
|
Chemical Change |
h |
|
change of state from a solid to a liquid with the addition of energy |
Melting |
|
the change of a substance from a liquid to a gas |
Evaporation |
|
the conversion of a liquid to a vapor |
Boiling |
|
the change of a state from a liquid to a solid |
Freezing |
|
the change of state from a liquid to a solid |
Condensation |
|
the process in which a solid changes directly into a gas |
sublimation |
