What is the current model of the atom?
The Quantum Model or the Electron Cloud Model discovered by Schrodinger and Heisenburg. Shows us s, p, d, f electrons

The element copper (Cu) has two naturally occurring isotopes, copper-63 (62.930 amu) and copper-65 (64.928 amu). The average atomic mass of copper listed on the periodic table is 63.55 amu. Of these two isotopes, this one is the most abundant for this reason
Copper-63 because the average atomic mass of the element is closer to its mass

What are the names of the 4 quantum numbers and what do they tell us?
n - principal quantum number - tells us the energy level of the electron
l - angular momentum quantum number - tells us the shape of the orbital the electron is in (s, p, d, f)
mL - magnetic quantum number - tells us the orientation in space of the orbital
ms - spin quantum number - tells us the spin of the electron

Who developed each of the following models and what is the limits and merits for the planetary model?
Solid Sphere - Dalton/Democrateous
Plum Pudding Model - J. J. Thompson
Nuclear Model - Rutherford
Planetary Model - Bohr
Quantum Model - Schrodinger/Heisenburg
