The velocity of an electron in the outermost shell is?
Correct answer: A. Minimum
- A. Minimum
- B. Maximum
- C. Intermediate
- D. None of these
Explanation
Electrostatic Attraction: Electrons in the outermost shell are furthest from the nucleus. They experience the weakest electrostatic attraction from the positively charged nucleus.Lower Binding Energy: Because of the weaker attraction, the outermost electrons have lower binding energy (energy required to remove them).Lower Velocity: Lower binding energy implies lower kinetic energy, and therefore, lower velocity.

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.
