Which of the following elements has the maximum number of atoms in their molecular form?

In Sulphur (S), the molecular form is S8, meaning each Sulphur molecule contains 8 atoms. This gives Sulphur the maximum number of atoms in its molecular form compared to Phosphorus (P4), which has 4 atoms, and Argon (Ar) and Neon (Ne), which are noble gases and exist as monoatomic (single atom) elements under standard conditions. Therefore, Sulphur has the most atoms in its molecular form.
