NEET Chemistry Orbitals MCQ Question
Which of the following statements about orbitals and quantum numbers is correct?
The value of m_l can be derived from the principal quantum number n.
For p orbitals, there are three possible orientations corresponding to m_l values of -1, 0, and +1.
The shape and energy of all orbitals within the same subshell are identical.
The maximum number of electrons in an s orbital is four.
Correct Answer
Detailed Explanation
Statement B is correct as it notes the three orientations of p orbitals corresponding to m_l values of -1, 0, and +1. Statement A is incorrect because m_l values depend on l, not n. Statement C is incorrect because orbitals differ in orientation but not in shape or energy within the same subshell. Statement D is incorrect as an s orbital can hold a maximum of 2 electrons.
