Definition of KF
KF, also known as potassium fluoride, is a chemical substance with the formula KF. Its English name is also Potassium Fluoride. In the molecular structure of KF, potassium atom (K) and fluorine atom (F) bond together to form a molecule. The atomic masses of potassium and fluorine are 39.1 and 18.9984 respectively. Once formed, the KF molecule dissociates into two ions: K+ ion and F- ion. -
