When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation—an ion with a net positive charge. For example, the element sodium loses one electron to become a cation:
Sodium bicarbonate molecules feature one sodium cation and one bicarbonate anion. Here, an ionic bond is formed between the positively charged sodium ion and the negatively charged oxygen (which is singly bonded to the central carbon and not bonded to a hydrogen atom).

Jan 15, 2024 · If the cation can not have more than one possible charge, use the name of the cation and the name of the anion. Examples of this would be KBr, which is potassium bromide, NaNO3, which is sodium nitrate, and (NH4)2S, which is ammonium sulfide.
Sep 2, 2017 · Sodium bicarbonate molecules consist of a sodium cation and a bicarbonate anion. An ionic bond forms between the positively charged sodium ion and the negatively charged oxygen, which is singularly bonded to the central carbon and remains unbound to a hydrogen atom.
Cations and anions. When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation —an ion with a net positive charge. The opposite process can also occur.
May 20, 2018 · Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.
