Net charge of a non-ionized atom

Describe the net charge of a non-ionized atom?

E

Expert

Verified

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).
