What is the difference between a compound and mixture

Here is what i got from my notes, hope this helps.

Mixture components keep their identities.
Mixture components CAN be separated PHYSICALLY
Homogenous Mixture: You CAN NOT the different parts (phases) of the mixture
Heterogeneous Mixture : You CAN SEE the different parts (phases) of the mixture easily
A solution is a HOMOGENOUS MIXTURE of particles so small that they cannot be seen and CANNOT be filtered out
A compound is something that is made from something that can be separated from 2 things.
It is a mixture and has chemical bonds.

Notice the subscript went from 83 to 84 and the 214 stayed the same that means it was beta decay.
