Read each question carefully and provide your answers in the spaces provided. For drawing electron dot diagrams, ensure all valence electrons are represented correctly.
1. The electrons involved in chemical bonding are called electrons.
2. The group number on the periodic table often indicates the number of electrons for main group elements.
3. An atom is most stable when its outermost shell contains valence electrons, a concept known as the octet rule.
4. How many valence electrons does a Nitrogen (N) atom have?
2
3
5
7
5. Which of the following elements would have an electron dot diagram with two dots?
Boron (B)
Magnesium (Mg)
Oxygen (O)
Chlorine (Cl)
6. Draw the electron dot diagram for a Sulfur (S) atom.
7. Draw the electron dot diagram for a Potassium (K) atom.
8. Draw the electron dot diagram for the Oxide ion (O²⁻).
