Bonding basicsComplete the chart using your atomic structure cards When an atom gains or loses an Electron it is called an Ion
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. X X X X + - + - X + - + - X X X + - + - X X X X X + - + - X X + - + - X X + - + - Chlorine atom + - + - + - + - + - - + -

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 ____________. NEGATIVE POSITIVE 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.
