Niels Bohr said, "Anyone who is not shocked by quantum mechanics has not understood it."

Solution 108P

Niels Bohr said, "Anyone who is not shocked by quantum mechanics has not understood it." because quantum mechanics gives information about two important facts like dual nature of electron and the second one is about the quantization of energy. This can be explained as follows:-

• Quantum chemistry is the application of quantum mechanical principles and equations to the study of molecules. In order to understand matter at its most fundamental level, we must use quantum mechanical models and methods.
• There are two aspects of quantum mechanics that make it different. The first is the concept of wave and particle duality; i.e the notion that we need to think of very small objects (such as electrons) as having characteristics of both particles and waves.
• The Second is, quantum mechanical  models correctly predict that the energy of atoms and molecules is always quantized, meaning that they may have only specific amounts of energy.
• Quantum chemical theories allow us to explain the structure of the periodic table, and quantum chemical calculations allow us to accurately predict the structures of molecules and the spectroscopic behavior of atoms and molecules.
