Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge.

2025年3月2日 · 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. …

2021年11月20日 · In chemical reactions, ions form when atoms or molecules gain or lose valence electrons. Only nuclear reactions change the number of protons in a chemical species. The …

Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions).” Simple ions include Na +, Ca 2+, and Cl –. Polyatomic ions include (NH 4) +, (CO 3) 2-, and …

Ions form when atoms lose or gain electrons. Ionic compounds have positive ions and negative ions. Ionic formulas balance the total positive and negative charges.

During the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions (Figure 3.3.1 3.3. 1). Figure 3.3.1 3.3. 1: (a) A sodium atom (Na) …

The ions that contain a greater number of protons than electrons are known to hold a net positive charge. These ions are commonly referred to as cations. On the other hand, the ions that …
