WebJul 3, 2024 · Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge. If the chemical species has … WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation. birmingham fence companies

WebTo find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound. In this video, we'll walk through this process for the ionic compound calcium bromide. Created by Sal Khan. WebSep 16, 2024 · An anion is an ion with negative charge, meaning it has more electrons than protons. Anions are formed when an atom gains one or more electrons: the gain of the negatively-charged electron (s) results in an overall negative charge. Are anions formed by metals or nonmetals? WebApr 14, 2024 · An atom becomes an Ion (a) if it gains one or more electron (s) or (b) if it loses one or more electron (s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron (s) it becomes positively charged and is called a cation.
