Read each question carefully and answer to the best of your ability. Use your knowledge of electron dot diagrams and valence electrons to complete the tasks.

1. What do the dots in an electron dot diagram represent?

Protons

Neutrons

Valence electrons

Core electrons

2. How many valence electrons does an atom of Oxygen (O) have?

3. Electron dot diagrams are also known as structures.

4. The number of valence electrons an atom has is typically equal to its group number on the periodic table (for main group elements).

5. Draw the electron dot diagram for a Carbon (C) atom.

6. Explain why valence electrons are important in chemical bonding.

7. All atoms try to achieve 8 valence electrons to become stable (octet rule).

True

False

8. An electron dot diagram shows all the electrons in an atom, not just the valence electrons.

True

False
