An ion is an electrically charged stature formed by an atom or group of atoms losing or gaining one or a few electrons. This process is called ionization. The energy required or emitted by the ionization process is known as ionization energy.
In a chemical reaction, the atom of a metallic element loses its outermost electron, and the non-metallic atom gains an electron, thus giving charge to the atom or cluster of atoms participating in the reaction. Charged atoms are called ions, positively charged atoms are called cations, and negatively charged atoms are called anions. Anions and cations form uncharged compounds due to electrostatic action.

Material characteristics: The chemical valence of a substance called sub in chemistry must be lower than its highest chemical valence, but it is not necessarily the chemical valence in the middle (for example, the chemical valence of chlorine is -10 + 1 + 3 + 5 + 7 valence is the highest chemical valence of the liquid.
Okay, the ion concentration is only the number of ions per unit volume of solution, for example, if there are 2na sodium ions in 1 liter of saline, then the concentration of sodium ions is 2mol l, if there are 3nage1 sodium ions in 1 liter of saline, then the concentration of sodium ions is 3mol l, the charge carried by the example refers to a single one, for example, 1 sodium ion has 1 unit positive charge, and 1 magnesium ion has 2 units of positive charge! >>>More
