Some students made three claims about the bonding in a molecule of ammonia, $\text{NH}_3$. 1. Because a nitrogen atom has three outer electrons, every outer electron takes part in bonding. 2. A nitrogen atom has five outer electrons, so two of its outer electrons are not used in bonding. 3. A nitrogen atom shares electrons with each of the three hydrogen atoms. Which of these statements about bonding in ammonia are correct?
- A1 and 3
- B1 only
- C2 and 3
- D2 only
