Dempsters mass spectrometer has number of zones / parts_________________?
Correct answer: A. 5
- A. 5
- B. 4
- C. 3
- D. 2
Explanation
In the conventional description of Dempster's mass spectrometer, the apparatus is divided into five zones or parts, including ionisation, electric and magnetic fields, detection, and the vacuum arrangement. Hence the expected number is 5 parts. The likely mistake is choosing 3 by counting only the main working regions and ignoring the other apparatus zones.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
