4.6: Ionic Formula Writing - Chemistry LibreTexts
Chemical formulas for ionic compounds are called ionic formulas. A proper ionic formula has a ion and an anion in it; an ionic compound is never formed between two ions only or two anions only. The key to writing proper ionic formulas is simple: the total
Chemical reaction - Wikipedia
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.

Ionic Bonds - M Physical
They are formed between two elements with a large difference in electronegativity, like a metal and nonmetal. Molecules with similar electronegativities share their electrons and form covalent bonds. Because bromine has a much higher electronegativity than potassium, it will fully take an electron from potassium to form a complete octet, leaving potassium also with a complete octet.

Ionic liquid - Wikipedia
An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 C (212 F). While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs.
