WebWhen a metal forms an ionic compound, the formula of the compound produced depends on the energetics of the process. On the whole, the compound formed is the one in which most energy is released. The more energy released, the more stable the compound. There are several energy terms to think about, but the key ones are: WebMetals are known for conducting electricity and heat well. Many metals are strong, shiny, and hard. They are also often malleable, meaning they can be shaped without breaking or cracking. Types of Metals. There are all sorts of metals.
