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 the 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 |
|
Density |
A measurement of how solid something is, specifically it is 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 |
|
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 particles of an atom that carries a neutral charge; found in the nucleus |
|
Electrons |
the negatively charged particles of an atom; found 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 it’s container |
|
Gas |
the state in which matter expands to occupy the space around it or whatever volume is available |
|
Physical Property |
characteristics 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 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 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 state from liquid to solid |
|
Condensation |
the change of state from gas to liquid |
|
Sublimation |
the process in which a solid changes directly into a gas |
