Guida verificata passo dopo passo1
Understand that a chloride ion (Cl^-) is formed when a chlorine atom gains an electron.
Recall that a neutral chlorine atom has no net charge because it has equal numbers of protons and electrons.
When chlorine gains one extra electron, it now has one more electron than protons, resulting in a net negative charge.
The charge on the chloride ion is therefore negative one, which is written as \$1^-$ or simply $-$.
Conclude that the correct charge on a chloride ion is \$1^-$, not positive or zero.
