B) Two of the three statements are true.
C) Only one of the statements is true.
D) None of the statements is true.

Question

1) True - An electron configuration does indeed specify the distribution of electrons among the various atomic orbitals, indicating subshell occupancy.2) False - The atomic number equals the number of protons, and for atoms with equal numbers of protons and neutrons, the mass number is roughly double the atomic number, not the atomic number being double the mass number.3) False - Neon has a total of 10 electrons, not 12, and all its occupied orbitals are completely filled, but the statement incorrectly states the number of electrons.
