2. Subatomic Particles
An atom is composed of three subatomic particles.
Proton:
Positive charge
Located within the nucleus of the atom
Electron:
Negative charge
Located circling around the nucleus in probable paths
Neutron:
No charge
Located within the nucleus of the atom beside the protons
Particle mass is measured in unified atomic mass units, their symbol is defined by a
u.

3. Ions
An ion is an atom with a charge
Charge is changed by neutron amount
Subtract protons from isotopes to find number of neutrons

4. Orbital

Molecular Orbital
Spinorbitals Theory Niels Bohr
1)Everything is a solid atom
2)Everything is made from
atoms
Energy Level
Proposed that different energy levels
existed in an atoms electron shell

6. Electron Energy Field
An Electron is contained within an energy field.
Each energy field has a specific number of electrons that can be contained within it.
Atoms gain or lose electrons to create a more stable valence shell
Max hold
Shell 1- 2 electrons
Shell 2- 8 electrons
Shell 3- 8 electrons
