The smallest particle in which an element can be divided, and still have the properties of that element.
Individual atoms, from two to thousands, combine to form these, which can be made up of the same type or different types of atom.
Pure substance that consists entirely of one type of atom. It can be a single atom or a extended structure with thousands of atoms.
A substance made up of atoms of two or more different elements joined by chemical bonds
Atoms from this group of elements usually do not attract to others to form molecules.
the force that holds two atoms together
A molecular structure made up of repeated pieces - from 10's to 10's of thousands - that can take many forms. In some structures, the same molecule repeats; in other structures, the same atom of a single element repeats.
Molecules that can connect to each other to create a larger structure.
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
state of matter
A physical property that describes matter as a solid, liquid, or gas.
Particles tightly packed and vibrate in place, doesn't take shape of container
Particles vibrate but can slide past each other and take on shape of container
Fast moving particles that are spread far apart and can escape a container
Energy of motion
Energy produced from atoms and molecules moving.
The transfer of thermal energy from one object to another.
tends to make the atoms or molecules move farther apart
tends to keep the atoms or molecules grouped together
A change from one state of matter to another from the addition or removal of thermal energy. The type of substance does not change.
The change in state from a gas to a liquid
The change in state from a liquid to a gas
The change in state from a solid to a liquid
The change in state from a liquid to a solid
A change in state from a solid to a gas without becoming liquid
The change in state from a gas to solid without becoming a liquid
the amount of force exerted per unit area of a surface
