Ionic bonding is a type of chemical bond formed by the electrostatic attraction between oppositely charged ions. In this case, potassium (K) loses an electron to become a positively charged ion (K+), while nitrogen (N) and oxygen (O) atoms share electrons to become negatively charged ions (NO3-).
These ions are then held together by their electrostatic attraction, forming the ionic compound KNO3. The strong attraction between the positively charged potassium ions and the negatively charged nitrate ions results in the formation of a stable ionic crystal lattice.
