Second, most atoms form ions of a single characteristic charge. When sodium atoms form ions, they always form a 1+ charge, never a 2+ or 3+ or even 1− charge. Thus, if you commit the information in Table \(\PageIndex{1}\) to memory, you will always know what charges most atoms form.

Atoms that lose electrons acquire a positive charge because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
3 mar 2020 · Cations and anions are the two types of ions. Ions have an imbalance of electrical charge, meaning they contain different numbers of protons and electrons. Cation have a positive electrical charge and have more protons than electrons. Anions have a negative electrical charge and have more electrons than protons.
29 lip 2022 · Positively charged ions are called cations, and negatively charged ions are called anions. Ions can be either monatomic (containing only one atom) or polyatomic (containing more than one atom). Compounds that contain ions are called ionic compounds.

Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.
Learning Objectives. By the end of this section, you will be able to: Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds.
