What is the relationship between
Atoms & Molocules

They are atoms that have the same atomic number but a diffrent atomic mass because the number of neutron differ.
-Atomic Mass - the # of P & N in the neculeus
-Atomic Num - the # of P in the Nucleus & E in the Atom
This is an exaple of?
Isotopes - They're all Hydrogen atoms but with diffrent Atomic Mass's (number of Neutron differs)
