atomic mass - atomic #
# electrons + # protons
# protons - # electrons
Atomic number - atomic mass
13
Half life is most associated with
Nuclear decay
Nuclear fission
Nuclear fusion
14
Strong Force
A force that can lift a lot of weight
A made up force
Holds atoms together
15
To find the weighted mass you multiply
mass by the % abundance
Mass by # of protons
number of protons by the number of neutrons

Valence electrons are
the electrons in the outermost shell
the dots Pacman eats
the protons that escape the nucleus
the electrons that ran away from home
20
Nuclear fusion
takes a lot of energy and is hard to achieve on earth
takes little pressure and low temperature
happens to large and unstable atoms
releases very little energy
