First real chemist.
Came up with the periodic table and put them in order.
Came up with the atomic theory.
The temperature that a liquid boils at.
The point in which liquid freezes at.
When water forms on something.
When water evaporates into the air.
The point in which dew forms on the ground.
The point in which something melts at.
A very small thing that everything is made out of.
The inside of an atom that is like the control center of something.
Has mass and takes up space.
A chemical substance that is present at the start of a chemical reaction.
A solid thing that has a definite volume and doesn't take the shape of its container.
Atom bouncing around wildly random motion, and takes the shape of its container.
a property used to characterize materials in reactions that change their identity
a property used to characterize physical objects
Negatively charged part of an atom. Has almost no mass.
Part of the periodic table and can react with other elements to make new things.
a tiny piece of something
Table that holds all of the elements in rows and columns.
change that is done chemically
a change that is done physically
something visible that by association or convention represents something else that is invisible
(chemistry) a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight
something that is mixed together to make something
particle model of matter
A scientific descripition of many different features of matter; according to the particle model, all matter is made up of extremely tiny particles, and each pure substance has its own kind of particle, different from the particles of other pure substances
conservation of matter
in any chemical reaction matter changes form; it is neither created nor destroyed.
a chemical substance formed as a result of a chemical reaction
molecule sliding past each other and takes the shape of its container.
