2. Steps Find the element’s # of Valence Electrons by looking at its Group #. Write the element’s chemical symbol. Starting at the top and moving clockwise, add valence electrons until all sides are filled. If each side is filled, begin pairing the electrons.
3. Example – Step 1 Find the element’s # of Valence Electrons by looking at its Group #. Sodium Oxygen Group 1 Group 16 (6A) 1 Valence Electron 6 Valence Electrons
4. Example – Step 2 Write the element’s chemical symbol. Sodium Oxygen Na O
5. Example – Step 3-4 3) Starting at the top and moving clockwise, add valence electrons until all sides are filled. 4) If each side is filled, begin pairing the electrons. Na O Sodium has 1 valence electron. Movingclockwise, add valence electrons. Since all sides are filled, being again at the top and work clockwise. Oxygen has 6 Valence Electrons.
