If the ground-state configuration of an atom is 1s²2s²2p⁴, what is the atomic number of the atom? A) 14 B) 10 C) 8 D) 4 E) 3

Question

Quizplus · Accepted Answer

The numbers in the electron configuration represent the number of electrons in each orbital. Counting the number of electrons, we have 2 in the 1s orbital, 2 in the 2s orbital, and 4 in the 2p orbital, giving a total of 8 electrons. This corresponds to the atomic number of oxygen (O).
