ANSWER
Pottasium Chloride. Its chemical formula is KCl , consists of one potassium (K) atom and one chlorine (Cl) atom. An Ionic compound is made of a metal element and a nonmetal element. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt.
Chemical bonding is the process that links elements together to form compounds. KCl is an example of ionic bonding.There is formation of ionic bond when the compound has bond between metal and non-metal. As there is no sharing of electrons, but total transfer, here potassium loses its electron and chlorine accepts is completely filling its second orbit, the ionic bond in KCl is formed.
conclusion: hence option (A) is correct
