|
ELEMENT |
basic building blocks of matter; can not be broken down to a simpler substance, consists of atoms of only one type |
|
|
ATOM |
the smallest particles of an element that has the chemical properties of that element, these are building blocks of life |
|
|
MASS |
the amount of matter in a substance, you can measure mass using 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 something takes up |
|
|
MATTER |
anything that has mass and takes up space (has volume) |
|
|
NUCLEUS |
the center of an atom that contains both protons and nuetrons |
|
|
PROTONS |
the positively charged particles of an atom; found in the nucleus |
|
|
ELECTRONS |
the negatively charged particles of an atom; found outside the nucleus |
|
|
NUETRONS |
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 maintain a fixed volume and shape |
|
|
LIQUID |
the sate i 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 on state to another without a change in chemical composition (solid, liquid, or gas) |
|
|
CHEMICAL CHANGE |
Results in the formation of one or more new substances; a change can not be reversed |
