Answer :
The correct order of orbital filling based on relative energy is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p. Thus, the correct answer is option D.
The correct choice is:
D) 1s 2s 2p 3s 3p 4s 3d 4p
The order of orbital filling in an atom is based on the energy levels of the orbitals.
The relative energy of the subshells determines this order, starting from the lowest energy orbital (1s) and moving to higher energy orbitals.
Following the aufbau principle, the electrons fill the orbitals in increasing order of energy:
1s 2s 2p 3s 3p 4s 3d 4p
For instance, after the 3p orbitals are filled, the next orbital to be filled is the 4s, even though it is in a higher principal quantum number (n = 4) compared to the 3d orbitals.
The complete question is as follows:
Which of the following properly represents the order of orbital filling based on the relative energy of the orbitals?
Multiple Choice
A) 1s 2s 3s 4s 2p 3p 4p 3p
B) 1s 2s 2p 3s 3p 3d 4s 4p
C) 1s 2s 2p 3s 3d 3p 4s 4p
D) 1s 2s 2p 3s 3p 4s 3d 4p
The properly represents the order of orbital filling based on the relative energy of the orbitals is:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p.
What Is Orbitals
Orbitals are the regions or regions in space around the atomic nucleus that have the highest probability of finding electrons. In the arrangement of the orbital diagram, an electron is symbolized by an arrow facing up which represents an electron with spin +½, or facing down which represents an electron with spin -½. To mark the distribution of orbitals within the atom, these arrows are placed on a horizontal line, in a circle, or generally in a box.
Orbital diagrams are used to facilitate the determination of the value of the quantum numbers, namely the magnetic quantum number and the spin quantum number.
