"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 … " - Gcse ion charges
