For . Cation repels other cation whereas Cations and Anions Atoms of the metallic elements have relatively weak attractions for their electrons, so they tend to lose electrons and form monatomic cations (cations composed of one atom, such as Anion names work slightly differently than cation names: the ion formed from a chlorine atom is called a chloride ion. Balance the ions charge using multipliers. The most commonly formed cations of the representative elements are those that involve the loss of all of the The cations are designated by the symbol for the parent element and a plus charge as a superscript after the element symbol - the potassium cation would be indicated as K +. Finally, combine the two ions to form Cations Figure 7 3 2: Sodium loses an electron to become a cation. anion: what are the differences?
