The inorganic compound formed between potassium and chlorine atoms is potassium chloride KCl . My reasoning is based on the following:1. Potassium K is an alkali metal belonging to Group 1 of the periodic table, which means it has one valence electron in its outermost shell. It tends to lose this electron to achieve a stable electron configuration, forming a +1 ion K+ .2. Chlorine Cl is a halogen belonging to Group 17 of the periodic table, which means it has seven valence electrons in its outermost shell. It tends to gain one electron to achieve a stable electron configuration, forming a -1 ion Cl- .3. When potassium and chlorine atoms react, potassium transfers its one valence electron to chlorine. This results in the formation of a potassium ion K+ and a chloride ion Cl- .4. The electrostatic attraction between the positively charged potassium ion K+ and the negatively charged chloride ion Cl- leads to the formation of an ionic bond.5. The compound formed by the ionic bond between potassium and chlorine is potassium chloride KCl , which is an ionic compound.
