Ionic Bonding Speed Dating:
Directions:
1. Each student will be given an index card with an element name. Step one is to record your personal information in the box below
for your atom.
2. When time is called, you will start your “date” with the element across from you. Together, you must determine what the chemical
formula of the new compound would be, the name of the compound, and the electronegativity difference to determine the bond type.
Is the pair truly ionic?
