Q: How many maximum electrons can be present in third or m-subs heel?
  • A. 32
  • B. 8
  • C. 18
  • D. 2
Correct Answer: Option C - The circular baths around the nucleus in which electrons revolve around the nucleus are calved orbits. Orbits from nucleus to the circumference are named as K.L.M.N........ having respective n valve 1, 2, 3, 4.......... orbits are also calved sheel. Each sheel can accommodate maximum 2n² electrons. Hence, in M-shell (n=3) can contain maximum 2 (3)2 = 18 electrons.
