Where are these subatomic particles found in an atom?
Neutron + proton = nucleus , Electron = energy levels

How do you figure out percentage abundances?
You times the percentage % by the mass of each isotope add them together and divide by 100

Complete this example, 63 Cu (69.1%) and 65 Cu (30.9%)
(69.1 x 63) + (65 x 30.9) = 6361.8 / 100 = 63.618 = 63.6

Do isotopes have the same or different chemical and physical properties?
Chemical - SAME as the number of electrons stay the same and that is what determines chemical properties PHYSICAL - DIFFERENT as there are a different number of neutrons which can change the density etc

How do you calculate relative mass without % abundance?
You times the mass x abundance of each isotope then divide by all the abundances added together
