What is the difference between ferromagnetism and paramagnetism?
What is

3 principles / rules when determining how the electrons are distributed in an atom
What is
Hund's Rule - Electrons spread out as far as possible from each other. they occupy orbitals singly and in parallel spin.
Pauli's exclusion principle - Only a maximum of two electrons can occupy one orbital and must have opposite spin.
Aufbau principle - Electrons occupy the lowest energy orbital

Explain why Copper sulphate breaks apart when hit by a hammer, but solid Copper flattens out.
What is
Copper is a metallic substance and is surrounded by a sea of delocalized electrons that can move around. These electrons can shift to allow bending. (they are very malleable)
Copper sulphate has a strong ionic, directional bond
If the bonds are broken, the whole substance will break
