Net charge of a non-ionized atom
Describe the net charge of a non-ionized atom?
Expert
In an atom, number of protons is equivalent to number of electrons and that one proton has the alike positive charge value as an electron does a negative charge value. Thus, I am supposing that all the atoms have zero, no charge, none, squat. Also, Non-ionized means an atom hasn’t suffered electron exchange, so a non-ionized atom is actually just an atom (i.e. word dismissal). That is all, I know from the AS level Chemistry, so I don't recognise if it's the similar thing as more advanced chemistry (for university).
