Which statement concerning the electrons surrounding the nucleus of an atom is NOT correct?

a) When 2 electrons pair together, they have opposite spins.

b) The number of the electrons in an isolated neural atom is equal to the atomic number

c) The second main energy level can have any number of electrons up to ten

d) The attraction of the electrons by the nucleus helps determine the size of the atom

e) No more that 2 electrons can occupy a single orbital

I thought c was wrong.
