1. Mineral Chemistry

2. Atoms
An atom is the smallest particle of matter that contains the characteristics of an element.
Atoms contain subatomic particles:
Protons: Positively charged, found in the nucleus
Electrons: Negatively charged, found in the outside the nucleus.
Neutrons: No charge, found in the nucleus.
Atomic number: The number of protons in the nucleus of an atom.
Atomic Mass: Number of protons + neutrons

10. Ionic Bond

14. Bonding forms Minerals
Ions ---- Molecules ---- Minerals ---- Rocks

15. ION
An ion is an atom or molecule which has lost or gained one or more electrons, giving it a positive or negative electrical charge.

16. When a group of ions or molecules form a solid structure, called a lattice, a mineral compound may form.
