A mineral is made up of an element or elements bonded together
An element is a substance that CANNOT be broken down into other substances by ordinary chemical methods
An atom is the smallest unit of a substance that retains properties of that element.

2. Neutrons(0 net charge)
3. Electrons (-charge)
What forms the nucleus of an atom?

equal or not equal?
the outermost shell of a atom is it's _____ electron
chemical reactions involve only the outermost shell, _____ electrons
What are isotopes?
atoms of an element with different numbers of neutrons
Isotopes may be either stable or unstable.
isotopes retain all of their protons and neutrons over time
unstable or radioactive isotopes spontaneously ____ subatomic particles from their nuclei
stable isotopes can be used to track _______ over time
What is an Ionic Bond?
when the "transfer"of valence electrons from one atom to another occurs
What is a Covalent Bond?
when the "sharing" of valence electrons among adjacent atoms occurs
What is a Metallic Bond?
when electrons flow freely throughout metals which results in high electrical conductivity
What is chemical bonding controlled by?
