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.
