Quantum theory, stationary orbits, and quantum mechanical models were groundbreaking ideas in physics, introduced by Planck, Bohr, and Schrödinger, respectively. The Pauli Exclusion Principle is essential for understanding electron configuration in atoms.
Let’s break down the matching step by step:
Step 1:
Quantum theory is associated with Max Planck as he is regarded as the father of quantum theory. Hence, 1 matches with B.
Step 2:
Stationary orbits refer to Niels Bohr’s model of the atom, where electrons revolve in stable orbits without radiating energy. Hence, 2 matches with A.
Step 3:
Quantum mechanical model of an atom is closely related to Erwin Schrödinger, who developed the wave equation that describes the quantum state of an electron. Hence, 3 matches with D.
Step 4:
The Pauli Exclusion Principle, which states that no two electrons can have the same set of four quantum numbers, is associated with Wolfgang Pauli. Hence, 4 matches with C.
Step 5:
Conclusion:
The correct answer is (3) 1-B, 2-A, 3-D, 4-C, as each concept is correctly matched to its corresponding scientist.
