Ionic Bonds Ionic bonds are formed by one atom transferring electrons to another atom to form ions. Ions are atoms, which have lost or gained electrons and therefore have a negative or positive charge

The atom losing electrons forms a positive ion and is usually a metal. Sodium atom

The atom gaining electrons forms a negative ion and is usually a non-metallic element Chlorine atom X XX XX X X X X X X XX XX X X

Answer these questions: An atom that gains one or more electrons will have a ____________________ charge. An atom that loses one or more electrons will have a ____________________ charge. An atom that gains or loses one or more electrons is called an ____________. POSITIVE NEGATIVE ION

What is an ionic bond? Atoms will transfer one or more ________________ to another to form the bond. Each atom is left with a ________________ outer shell. An ionic bond forms between a ___________ ion with a positive charge and a ________________ ion with a negative charge attracting each other. Example: Sodium + Chlorine ELECTRONS COMPLETE METAL NONMETAL X XX XX X X X X X X XX XX X X Sodium chloride
