difference between molar entropies?

Why does lead have a higher molar entropy than carbon?

lead has a significantly higher amount of particles( protons, neutrons, and electrons) than carbon which means it has a higher degeneracy, and thus a higher entropy.

More particles -> higher degeneracy -> more entropy

Standard entropies tend to increase with increasing molar mass.

For each mole of lead, there are more protons, electrons, and neutrons than in carbon, so on a sub-atomic level, there is more entropy because these particles' movements contribute to the atom's overall entropy.

Lead has more molecules and since it is a larger number, it has more electrons, protons, and neutrons leading it to a larger mass as well

Lead is a more complex molecule so it has more electrons, neutrons, and protons in one mole. Since there are more particles in lead, there is more degeneracy and therefore more entropy.
