![]() Whether an atom forms a cation or an anion depends on its position on the periodic table. Predicting Cations and Anions based on the Periodic Table Ions like hydroxide, dichromate, sulfate, and ammonium that contain more than one type of element are called polyatomic ions and are discussed in more detail in another article. Because electrons are added to form an anion, the anion of an atom is bigger than the neutral atom.Įxamples of anions include the following: What is an anion? An anion is an ion that has gained one or more electrons, giving a net negative charge. Because one or more electrons are removed to form a cation, the cation of an atom is smaller than the neutral atom.Įxamples of cations include the following: ![]() What is a cation? A cation is an ion that has lost one or more electrons, giving a net positive charge. There are two types of ions: cations and anions.Ī cation has a net positive electrical charge, which means it has more protons than electrons.Īn anion has a net negative electrical charge, which means it has more electrons than protons. Ions are identified by a superscript that shows the sign and size of the electric charge – for example Ca 2. Ions form when atoms move into a more stable electron configuration. They contain different numbers of protons and electrons. The definition of an ion is a particle, atom, or molecule with an imbalance of electrical charge.

Elements located more to the left and toward the bottom of the non-metals will appear first in the compound name. When determining which element should be first, you must reference the periodic table. The suffix -ide is attached to the second element in the compound to complete the name. ![]() The prefix for one, mono-, is only applied to the second element in the name, assuming that it has no subscript (one atom per molecule). Conventions for naming these compounds require that prefixes be used to denote the subscript of each element in the compound, telling the number of atoms in the name. Binary molecular compounds contain two non-metal elements joined by covalent bonds. ![]()
