What is the correct order of the following orbitals in terms of increasing energy?

A. 1s 2p 4s 3d
B. 2p 3d 1s 4s
C. 4s 3d 2p 1s
D. 1s 3d 2p 4s

Answer :

Final answer:

The correct order of the given orbitals in terms of increasing energy is 1s<3d<2p<4s.

Explanation:

The correct order of the following orbitals in terms of increasing energy is:

  1. Option d) 1s 3d 2p 4s
  2. Option b) 2p 3d 1s 4s
  3. Option c) 4s 3d 2p 1s
  4. Option a) 1s 2p 4s 3d

This order can be determined by considering the energy levels of atomic orbitals. The general trend is that the energy increases as the principal quantum number, n, increases, and within each energy level, the s orbital has lower energy than the p orbitals. However, this trend may not hold for larger atoms.
