Rules for Ionic Bonding
•
Ionic bonds form between metals and non-metals.
•
In writing the symbols for ionic compounds, use subscripts to indicate how many atoms of each element are
present.
•
•
In naming simple ionic compounds, the metal is always first, the non-metal second (e.g., sodium chloride).
Write the metal first and the non-metal second.
•
No prefixes.
•
Change the final syllable of the non-metal to say ide
Draw the electron dot diagrams and name the compound using the rules above.
