The ionic compound KF is known as potassium fluoride.
In this compound, potassium (K) is a metal that carries a positive charge (K+), while fluoride (F), derived from fluorine, is a non-metal that carries a negative charge (F–). When these two elements combine, they form an ionic bond due to the electrostatic attraction between the positively charged potassium ions and the negatively charged fluoride ions. The chemical formula KF indicates that one potassium ion pairs with one fluoride ion to create a neutral compound. Potassium fluoride is commonly used in various applications, including in laboratories and in the manufacturing of certain chemicals.
