Among the following, the incorrect statement is
Options
- Ano two electrons in an atom can have the same set of four quantum numbers
- B(b) the maximum number of electrons in the shell with principal quantum number, n is equal to n²+2
- Celectrons in an orbital must have opposite spin
- Din the ground state, atomic orbitals are filled in the order of their increasing energies
Correct answer
B. (b) the maximum number of electrons in the shell with principal quantum number, n is equal to n²+2
Step-by-step solution
Consider the following statements. (I) According to Pauli's exclusion principle, no two electrons in an atom can have the same set of four quantum numbers. Thus, statement (a) is correct. (II) The maximum number of electrons in the shell with principle quantum number, n = 2 n 2 Thus, statement (b) is incorrect. (III) Electrons in an orbital must have opposite spin, i.e. m s = + 1 2 and - 1 2 . Thus, statement ( c ) is correct. (IV) According to Aufbau principle, in the ground state of the atoms, the orbitals ar
