-An ion is an atom or group of atoms with a positive or negative charge.
-It's between a metal and a non metal
-Ions form when atoms lose or gain electrons to obtain a full outer shell:
~ metal atoms lose electrons to form positively charged ions
~ non-metal atoms gain electrons to form negatively charged ions
-These oppositely charged ions are strongly attracted to one another by electrostatic forces, called an ionic bond
Forming ionic bonds
-Positive and negative ions form when a metal reacts with a non-metal, by transferring electrons
-The oppositely charged ions are strongly…
