Asked in Premeth MDCAT 2025 — Work and Energy, Atomic Structure, Nouns 2025Moderate

The shape of P orbital is:

Correct answer: A. Dumbbell

  • A. Dumbbell
  • B. Spherical
  • C. Trigonal
  • D. None of the above

Explanation

The P orbital's dumbbell shape arises from its electron density distribution, with two lobes positioned along an axis and a node at the nucleus. This shape is a result of the orbital's wave function. S orbitals, in contrast, are spherical, and the term 'trigonal' is unrelated to atomic orbitals, typically describing certain molecular shapes. Therefore, options B, C, and D do not correctly describe the P orbital's shape.

About Shapes of Orbitals

Atomic orbitals are three-dimensional regions where an electron is most likely to be found, not fixed circular paths. The content covers the spherical s orbitals, dumbbell-shaped p orbitals, clover-shaped d orbitals, the orientations of orbitals, and how quantum numbers determine their shapes and energy levels.
