When an atom has an electric charge it is called an ion.

The charge of an unionized atom is negative.
An atom may have a positive charge, a negative charge, or no charge. If it has a non-zero charge, it is said to be an ion.
If it has a positive charge it is a Cation. If it has a negative charge it is an Anion.
The net charge? I'll assume you mean total/overall charge seeing as I have never heard such term... In an atom the number of protons is equal to the number of electrons and that one proton has the same positive charge value as an electron does a negative charge value. So I'm assuming that all atoms have no charge, zero, none, squat. Non-ionized also means the atom hasn't suffered electron exchange, so a non-ionized atom is really just an atom (which is word redundancy). This is what I know from AS level Chemistry, so I don't know if it's the same thing as more advanced chemistry (for university or something). Hope I helped

The nucleus of an atom has a positive charge.The protons in the nucleus of an atom are charged oppositely from the electrons in the cloud around them. By convention, their charge is defined as "positive" while the charge on the electrons is defined as "negative".

The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number. Since neutrons have no electric charge, the nuclear charge of the specified atom is 17 amu.
Zinc has 30 protons; the term "nuclear charge" is rarely used.
