The branch of physics which deals with the structure and properties of atoms as determined by electron outside the nucleus:
Correct answer: B. Atomic Physics
- A. Nuclear Physics
- B. Atomic Physics
- C. Particle Physics
- D. Bio Physics
Explanation
Atomic physics is the branch of physics that specifically deals with the study of atoms, which consist of a nucleus (containing protons and neutrons) and electrons orbiting the nucleus. Atomic physics explores the behavior of electrons outside the nucleus, electron configurations, atomic spectra, and the interactions between electrons and photons.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
