An example is the hydroxyl ion: (OH)-.
An anion has an overall charge of 1-.
Both. The ClO4 (i.e. the perchlorate) is a covalently bonded molecule that carries an overall charge of 1-. The Na (i.e. the sodium) is a single atom with an overall charge of 1+. The connection between the sodium and the perchlorate is an ionic bond since one is 1+ and the other is 1-.
The overall charge for any compound is balanced. The charge for Ag is +1, and the charge for chloride is -1. They cancel each other out.
Lithium has a charge of Li^+1, phosphite has a charge of PO3^-3. But overall, Li3PO3 would be neutral.
Neon's overall charge is negative.
Atoms, by definition, have a neutral charge because they must contain equal numbers of protons (+) and electrons (-). Each proton has a +1 charge and each electron has a -1 charge. When an atom loses an electron, it then becomes an ion and has 1 less electron than protons. This means that you have 1 more proton than electrons, and, therefore, more positive charge than negative charge. The ion will then have an overall +1 charge.

The overall charge on He is 0. It is a noble element.

because chlorine has 17 protons contributing to a +17 charge, 18 electrons have a -18 charge, 17-18 = -1 which is the overall charge of the ion
because the number of protons (which have a positive charge of +1) and the number of electrons (which have a negative charge of -1) are the same. when number of protons = number of electrons, overall charge = 0
