Answer:
A molecular formulae________
will tell you how many and what
kinds of atoms are in a molecule, but not how they are
arranged.
Called electron cloud or orbitals or in quantum mechanics it's called energy levels
Reason1: electrons on farther layers become free easyer
2nd reason: volume of atoms grows (from Helium to Xeon) so instead of boyle-mariot law equation (PV=vRT) is more accurate to use van der walls equations that adds to the boyle-mariot equation the volume occupied by the atoms of the gas to the volume of the space between the atoms P(Vm-b)=vRT
