How did scientists count exact number of electrons, protons and neutrons of an atom?
How do we know that hydrogen has 1 electron and oxygen has 8 electrons?
Dont these numbers just represent some kind of **ratio** of charge or something?
Or is it exact integer value representing countable number of things in atom?
In: 0
Its the exact “integer” value of a charge, an electron does not have the charge of 1 so its not literaly an interger but all atoms cores and its shell have some integer multiple of that charge.
