WebAug 3, 2024 · The overall charge on an ion shows the number of electrons that have been gained or lost to form the ion. Charges on ions are always shown as superscript numbers given after the chemical symbol for the atom or molecule. For example, an oxygen atom could gain one electron to become an oxide ion with a single negative charge which … WebIonic bonds are formed when metal elements react with non-metal elements. To continue with the above example, consider the formation of the \text{LiF} molecule. When \text{Li} and \text{F} react, the lithium atom is able to lose its outer electron and give it to fluorine. This creates one positive \text{Li}^{+} ion and one negative \text{F}^{-} ion. Both ions will …

Therefore a chlorine atom has 7 electrons in its outer shell. this atom needs one more electron to form an ion with a full outer shell. Hence the ion formed will have a negative charge (adding electrons is adding a negative charge).
