Question
The electronic configuration of carbon atom in the excited state is $1s^2 2s^1 2p^3$. Which of the following is/are incorrect statement(s) about it?
Answer: C
💡 Solution & Explanation
The configuration $1s^2 2s^1 2p^3$ has 4 unpaired electrons (one in 2s, three in 2p). Thus, stating there are "only two unpaired electrons" is factually incorrect. Therefore, correct answer is C.
