Nickel chloride is a Ionic compound composed of metal and nonmetal. Due to the nature of Chemical bond between these ions, it is called Ionic compound in nature. In this ionic bond, the metal provides electrons to the non-metal and carries a positive charge, while the non-metal receives electrons and carries a negative charge. Therefore, in the compound Nickel(II) chloride, nickel is a metal, and the outermost layer has two Valence electron while chlorine is a non-metal, and the outermost layer has seven Valence electron. Each chlorine atom obtains 1 electron from nickel, so nickel obtains+2 charges by providing 2 electrons to each chlorine atom. Each chlorine atom will obtain negative charges by accepting electrons to complete its octet.
