Matter

Anything that occupies space and has mass.

1

Four States of Matter

Solid - Liquid - Gas - Plasma

2

Element

A substance that cannot be broken down into other substances.

3

Compounds

Two or more elements in a fixed ratio.

4

Atomic Number

Tells one the number of protons in the nucleus of an atom.

5

Atom

The smallest unit of matter that retains the properties of an element. Consists of protons, neutrons, and electrons.

6

Ionic Bonding

An attraction between two ions with opposite electrical charges. An electron transfer happens, and a compound is formed.

7

Ion

An atom or molecule that has gained or lost one or more electrons, thus acquiring an electrical charge.

8

Covalent Bonding

An attraction between atoms that share one or more pairs of outer-shell electrons. Electron sharing occurs, and this creates molecules.

9

Hydrogen Bonds

A type of weak chemical bond formed when the partially positive hydrogen atom participating in a polar covalent bond in one molecule is attracted to the partially negative atom participating in a polar covalent bond in another molecule.

10

Chemical Reaction

A process leading to chemical changes in matter involving the making and/or breaking of chemical bonds.

11

Reactants

What goes into a chemical reaction.

12

Products

What comes out, the results, of a chemical reaction.
