Diameter of Hydrogen atom is?

Correct answer: A. 105.8 x 10⁻² Å

  • A. 105.8 x 10⁻² Å
  • B. 1.061 Å
  • C. 0.55 Å
  • D. 131.3 x 10⁻² Å

Explanation

The diameter of a hydrogen atom is indeed approximately 105.8 x 10⁻² Å. It's important to remember that atomic sizes are incredibly small and are often expressed in angstroms (Å), where 1 Å = 10⁻¹⁰ meters.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
