Question

Carbon has an atomic number of 6 (and an atomic mass of 12).  Which of these statements about the electron arrangement is true?

Answer

There are 6 electrons, 2 of which are in the first energy level, and 4 are in the highest energy level, know as the valence shell.

Answer

Electrons can be in any energy level depending on the energy level of the photon they have absorbed

Answer

There are 6 electrons in the valence shell, meaning carbon falls in group 6, the oxygen family.
