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)? _______________________________________________________________________

3. F and LiWhich 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)? _______________________________________________________________________

4. Mg and OWhich 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)? _______________________________________________________________________

5. B and NWhich 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)? _______________________________________________________________________

6. Ne and HeWhich 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)? _______________________________________________________________________

Directions: For # 7-10, demonstrate, using Skittles, a covalent bond between the following atoms:

7. F and HeHow many electrons are they sharing? ______________________Why are they sharing the electron(s)? ____________________________________

8. O and HeHow many electrons are they sharing? _________________________Why are they sharing the electron(s)? ____________________________________

9. N and Ne How many electrons are they sharing? _________________________Why are they sharing the electron(s)? ____________________________________

10. H and Ne How many electrons are they sharing? __________________________Why are they sharing the electron(s)? _____________________________________

Directions: Answer the questions below.

1) What is an ionic bond? __________________________________________________________________________________________________________________________

2) What is a covalent bond? _________________________________________________________________________________________________________________________ 3) Why are ions (charged particles) created in ionic bonds but not in covalent bonds? ________________________________________________________________________________________________________________________________________________

4) What is the charge of an ionic compound? ________________________________________________________________________________________________________________________________________________

5) What is the difference between an ionic and covalent bond? _____________________________________________________________________________________________________________________________________________________________________
