Question
The orbits in an atom are represented by
- X, Y, Z, ….
- P, Q, R, S, ….
- K, L, M, N, …....
- A, B, C, D, …...
Hint:
The energy levels or shells are represented as K, L, M, and N.
The correct answer is: K, L, M, N, …....
- The electrons are distributed in shells or orbits according to the energy level.
- The shells are represented by K, L, M, and N.
- The K shell is the first shell or energy level, the L shell is the second orbit, M and N shells are the third and fourth energy levels respectively.
