Every compound is a molecule but not every molecule is a compound.
What is a part of an atom that have a positive charge.
protons
electrons
neutrons
nucleus
These hang out in the nucleus and don't really affect the properties of the atom that much. They don't have any charge (so they can't use credit cards).
neutrons
protons
electrons
atomic numbers
These are what form chemical bonds as atoms share or take them from one another. They orbit the nucleus and have a negative charge (but they are still happy about things in general).
electrons
electron clouds
protons
neutrons
This is the central region of an atom and where protons and neutrons hang out (but the protons and neutrons still follow proper social distancing rules!).
