NEET Chemistry Orbitals MCQ Question
Which of the following statements about orbitals is correct?
The probability density |ψ|² is always positive and indicates where an electron is likely to be found.
All orbitals have the same energy regardless of their principal quantum number.
p orbitals have no angular nodes and are identical in shape and orientation.
Electrons in the same subshell are paired before each orbital is singly occupied.
Correct Answer
Detailed Explanation
Statement A is correct as the probability density |ψ|² is always positive and indicates regions where electrons are likely to be found. Statement B is incorrect because the energy of orbitals varies with the principal quantum number. Statement C is false as p orbitals have one angular node and differ in orientation. Statement D misrepresents Hund's rule, which states that electrons fill orbitals singly first.
