the reason that on the periodic table elements have decimal values is because they average the isotopes. the most common isotope may be 33 but is bot 35 and 36 are very common as well they average out into 34 or 35 being displayed on the periodic table.
@DirtyShots47 another reason that atomic masses have decimals is because the masses of individual isotopes are not whole numbers. Only carbon-12 has a mass of exactly 12 because it was defined this way. The mass of iron-56 for example is 55.93
One thing I have seen a lot of people misunderstand that I think is worth clarifying is that the "normal" version of an atom is still an isotope, so Hydrogen with 1 proton 0 neutrons in the nucleus is still an isotope of hydrogen (just very common)
@jmxbox: I would talk about "purpose" in physics, but what the neutron does is keep the nucleus stable. Imagine you have many protons in the nucleus, they're all really close and positively charged, so they repulse each other. With the protons alone, you wouldn't have enough binding forces to keep them bound. But there is also the strong nuclear force acting between all particles in the nucleus counteracting this repulsion, the neutrons only add to the strong force, because they aren't charged.
you need to do a vid on ion's where the atom is negativly or posativly charged from the eletron's rubbing off or being attacted like a pottasiom atom has a 2,8,8,1 struture but when the extra electron had rubbed off (the reaction it causes) it then become's a postivly charged pottasiom ion (K+)
It does change the properties, the new Hydrogen (proton and neutron) [or Deuterium] atom has a spin of 1 where as the Hydrogen only containing a proton had the spin of a half. This changes magnetic properties of the atom.
If it takes 6 electrons and 1 positron to make a proton, then how is it that one or more electron orbits a nuclues that is made up of electrons to begin with?
Isnt the orbit of electrons around the nucleus a lot like the spin of the planets around the stars?

so what is the purpose of neutrons? They do nothing, change nothing. They're neutral like Switzerland!
