Introducing chemical reactions. Chemists use symbols and formulae to represent elements, ions and compounds. The formula of an ionic compound can be deduced from the formulae of its ions. Calcium hydroxide contains Ca2+ and OH- ions: this is two positive charges and one negative charge.- [Instructor] In a previous video, we've introduced ourselves to the idea of an orbital, that electrons don't just orbit a nucleus the way that a planet might orbit a star, but really, in order to describe where an electron is at any given point in time, we're really thinking about probabilities, where it's more likely to be found and less likely to be found.
