what is the atomic number and atomic mass of an atom w/ 8 protons & 8 neutrons
atomic # = 8 & mass # = 8
atomic # = 16 & mass # = 8
atomic # = 11 & mass # = 23
atomic # 8 & mass # = 16
11
Dalton's atomic theory states
atoms are divisible
atoms of the same element can have different # of protons
some but not all elements are composed of atoms
chem rxns occur when atoms are separated, joined, rearranged
