An ionic compound is a compound between a metal and a non metal where the metal (normally from group 1 or 2) transferrs an electron to the non metal ( most commonly from group 6 or 7) . this is so that both atoms have a full outer shell of electrons. the metal gains a positive charge and the non metal a negative charge. they are held together by electrostatic forces of attraction. an example would be sodium chloride (salt) sodium is in group 1 and chlorine in group 7 so sodium transfers one electron :)
<em>What is an ionic compound? Write an example.</em>
Answer:
<em>Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include: sodium chloride: NaCl, with Na+ and Cl- ions.</em>
