Which element does the electron configuration 1s² 2s² 2p⁴ represent?

Question

Quizplus · Accepted Answer

The electron configuration listed in the problem has 8 total electrons, as represented by the superscripts of each subshell (2 + 2 + 4 = 8).
Assuming the charge of the atom is neutral, 8 electrons means this atom will also have 8 protons and, therefore, an atomic number of 8. So, the correct answer will be the element with atomic number 8, which is oxygen.
