Consider the model of a sodium atom. An orange circle labeled upper N a is surrounded by three concentric circles. The innermost ring has dots at the north and south positions. The next ring has eight dots, evenly spaced, with dots aligning with those in the inner ring. The outermost ring has one dot at the north position. Which feature does the model show accurately?

A) the size of the electrons in different shells

B) the shapes of the orbitals in different shells

C) the distribution of electrons in different shells

D) the orientation of the orbitals in different shells
