Detailed explanation-1: -Binary ionic compounds are composed of just two elements: a metal (which forms the cations) and a nonmetal (which forms the anions).
Detailed explanation-2: -Ions with opposite charges will attract one another creating an ionic bond. Such bonds are stronger than hydrogen bonds, but similar in strength to covalent bonds.
Detailed explanation-3: -The opposite charges on the ions cause the ions to bond, or be held together, by electrostatic forces. An ionic bond is a bond between ions where oppositely charged atoms attract each other and cancel their charges to produce neutral compounds.
Detailed explanation-4: -An ion is an atom that has different number of protons and electrons. An isotope is an atom of an element with a specific number of neutrons. Two different isotopes of the same element will have two different neutron counts.
