What is the relationship between
Atoms & Molocules
Atoms bond together to form 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)
What determines the chemical properties of the atom?
The number of electrons in the outermost level
What are the (3) basic types of
They are atoms that have bonded together
Thety donate or take on electrons
They are the most stable type of bod
