Chemistry Key Works

?
Ions
An atom or molecule with an electric charge due to the loss/gain of electrons
1 of 14
Cations
positively charged ions (loss of electrons)
2 of 14
Anions
Negatively charged ions (gain of electrons)
3 of 14
Ionic Bonding
A chemical bond formed between two ions with opposite charges. Ionic bonds form when one atom gives up one or more electrons to another atom. These bonds can form between a pair of atoms or between molecules and are the type of bond found in salts.
4 of 14
Covelant Bonding
A chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
5 of 14
Molecular Structure
The 3D arrangement of atoms in a molecule.
6 of 14
Solutions
Mixtures.
7 of 14
Solvent
The substance that does the dissolving.
8 of 14
Solute
The dissolved substance.
9 of 14
Solid
Lower energy molecules. Not compressible. Have a fixed shape and can't flow.
10 of 14
Liquid
Incompressible. Closely arranged particles which can flow.
11 of 14
Gas
High energy state of matter. Fast moving particles with a lot of space between them. Compressible
12 of 14
Endothermic Reaction
A reaction which takes in energy from the surroundings. Temperature decrease.
13 of 14
Exothermic Reaction
A reaction which transfers energy to the surroundings. Temperature increase.
