It is equal to the amount of charge in one coulomb.
and is the amount of charge that passes through a common 100-watt light-bulb in about one second.

Ion 2+=====
+1
Ionicity refers to whether a chemical is an ion or not. An ion is a molecule whose total number of protons do not equal the total number of electrons. There are two kinds of ions: -An "anion" is an ion that contains more electrons than protons. It has a negative charge. -A "cation" is an ion that contains more protons than electrons. This has a positive charge.
An ion that has more electrons than protons has a negative charge.
The number of electrons are required to predict the charge of the ion.

i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.
An ion that has more electrons than protons has a negative charge.
Consider an atom of oxygen in which the nucleus contains 8 protons and 8 neutrons. If it is doubly ionized, what is the charge of the oxygen ion and how many electrons remain in the ion?
A sodium atom contains eleven electrons and has a net neutral electrical charge, because the atom also contains eleven protons. A sodium ion contains only ten electrons and has an electrical charge of +1, because it also contains 11 protons.
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
The number of electrons are required to predict the charge of the ion.
It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+
Remember.. I f there are more electrons than protons in an ion the charge will be negative. Here there is a -4 charge because the electrons are higher than the protons, if it were the opposite the charge would be +4.
