Which one of the following statements about atomic structure and quantum numbers is incorrect? A) In a given atom, 18 is the maximum number of electrons having principal quantum number n = 3. B) The number of orbitals in a given f subshell is 7. C) For n = 4, the largest possible value of l is 3. D) For n = 4, the largest possible value of m_l is 2. E) The following set of quantum numbers for a single orbital is not allowed: n = 3, l = 1, m_l = -2.
