NEET Chemistry Quantum Mechanical Model MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following combinations correctly describes aspects of atomic structure and the behavior of light?

A

White light is composed of all visible wavelengths, and violet light is deviated more than red light when passing through a prism.

B

Electrons in a hydrogen atom possess different energies for different principal quantum numbers.

C

Rutherford's model proposed that electrons are evenly distributed in a positively charged sphere.

D

The Millikan oil drop experiment demonstrated that gravitational forces are negligible when measuring charge.

Correct Answer

Option A

Detailed Explanation

Statement A correctly describes the behavior of light as it passes through a prism, where violet light bends more than red light due to its shorter wavelength. Statement B is incorrect because hydrogen atoms have the same energy for the same principal quantum number regardless of the azimuthal quantum number. Statement C misrepresents Rutherford's model, which disproved Thomson's model of uniform electron distribution. Statement D incorrectly states the role of gravitational forces in the Millikan experiment, where electrostatic and viscous drag forces are significant.
