It is one negative (-)
The chlorine ion is in group 7 so it has a charge of -1.
The Chlorine Ion has charge of -1.
-1
The Chlorine Ion has charge of -1.
The valence of a monoatomic chlorine ion is 1 and its charge is -1.
Sodium is in group one, chlorine in group 7. This means that a Sodium ion has a charge of +1, and a Chlorine ion has a charge of -1.
A chlorine ion has one less electron, giving it a +1 charge.
A chloride ion is a chlorine atom that has gained one electron, and as such has developed a charge of -1.
Chlorine is an atom with a neutral charge, 0. Chloride is the chlorine ion with a charge of -1. You can tell the two apart because the chlorine atom is simply "Cl" whereas the chloride ion is denoted "Cl" with a superscript minus sign.
A chlorine ion will have a charge of -1. A chlorine atom gains one electron to form the more stable chloride ion, thereby incurring a charge of -1. There is now one more electron than proton in the chloride ion, as compared to the chlorine atom which is electrically neutral.
The chloride ion has a negative charge of -1.
it has 7 electrons in its outer shell, which means its charge is -1.
