Question

multiple choice

1. how many valence electrons does carbon have?

☐ 12
☐ 8
☐ 4
☐ 6

Explanation:

Carbon has an atomic number of 6. Its electron configuration is \(1s^2 2s^2 2p^2\). Valence electrons are the electrons in the outermost shell. The outermost shell (n = 2) has \(2s^2 + 2p^2 = 4\) electrons. So carbon has 4 valence electrons.

Answer:

C. 4 (assuming the options are labeled as A. 12, B. 8, C. 4, D. 6)
