Ionic and covalent bonding activity- with Skittles!

1. Name: ___________________________
Ionic and Covalent Bonding Activity
Materials: - 24 Skittles
-Electron diagram sheet
Directions: Using the electron diagram sheet and the Skittles, you will demonstrate the
structure of different atoms and how they would form chemical bonds in order to become
stable compounds. The Skittles represent the electrons. You will then answer the
questions below.
For # 1-6 Demonstrate, using the Skittles, an ionic bond between the following atoms:
1. Be and O
Which element gives away electrons? _________________
How many electrons are given away? _________________
What is the charge of each ion after the bond? ___________________
Why are the 2 ions bonded together (what attracts them to each other)?
_______________________________________________________________________
2. Na and H
Which element gives away electrons?_______________________
How many electrons are given away? _________________
What is the charge of each ion after the bond? ___________________
Why are the 2 ions bonded together (what attracts them to each other)?
