Read each question carefully and answer to the best of your ability. For drawing Lewis dot diagrams, represent valence electrons as dots around the element symbol.
1. Lewis dot diagrams show only the electrons of an atom.
2. The maximum number of valence electrons an atom can have is .
3. Atoms tend to gain, lose, or share electrons to achieve a stable outer shell, which is known as the rule.
4. How many valence electrons does an oxygen (O) atom have?
2
4
6
