Compound:A compound is when two or more different types of atoms bind together chemically, much like a band formed from different musicians.
Molecule:A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. It's like one song produced by our band analogy above.
Atomic Number:The atomic number represents the number of protons in an atom's nucleus - it's kind of like an artistโs ranking on the charts!
