Chapter 7: Problem 95

Identify the following individuals and their contributions to the development of quantum theory: Bohr, de Broglie, Einstein, Planck, Heisenberg, Schrödinger.

Short Answer

Expert verified
Bohr proposed the Bohr atom model, de Broglie introduced wave-particle duality, Einstein developed the theory of photoelectric effect, Planck introduced energy quantization and Planck’s constant, Heisenberg proposed the concept of uncertainty principle, and Schrödinger developed Schrödinger’s wave equation. These were their contributions to the development of quantum theory.

Step by step solution

01

Identify Bohr and his contribution

Niels Bohr was a Danish physicist who proposed the Bohr model of the atom where electrons travel in discrete orbits around the nucleus, and the energy levels of these orbits are quantised. This was a major step forward in the development of quantum theory.
02

Identify de Broglie and his contribution

Louis de Broglie was a French physicist who proposed that all matter, not just light, has both particle-like and wave-like properties. This concept, known as wave-particle duality, is a fundamental principle of quantum theory.
03

Identify Einstein and his contribution

Albert Einstein was a German physicist who, among many other things, developed the theory of photoelectric effect which stated that light behaves as particles called photons. This idea contributed significantly to the development of quantum theory.
04

Identify Planck and his contribution

Max Planck was a German physicist who introduced the concept of energy quantization and developed Planck’s constant, a fundamental concept of quantum theory.
05

Identify Heisenberg and his contribution

Werner Heisenberg was a German physicist who introduced the concept of the uncertainty principle, a fundamental principle of quantum mechanics that states it is impossible to know both the position and momentum of a particle at the same time.
06

Identify Schrödinger and his contribution

Erwin Schrödinger was an Austrian physicist who developed Schrödinger’s wave equation. This equation describes how the quantum state of a quantum system changes over time.

Most popular questions from this chapter

Only a fraction of the electrical energy supplied to a tungsten lightbulb is converted to visible light. The rest of the energy shows up as infrared radiation (that is, heat). A 75-W lightbulb converts 15.0 percent of the energy supplied to it into visible light (assume the wavelength to be \(550 \mathrm{nm}\) ). How many photons are emitted by the lightbulb per second? \((1 \mathrm{~W}=1 \mathrm{~J} / \mathrm{s} .)\)

What are the group and period of the element osmium?

What is electron configuration? Describe the roles that the Pauli exclusion principle and Hund's rule play in writing the electron configuration of elements.

An electron in a hydrogen atom is excited from the ground state to the \(n=4\) state. Comment on the correctness of the following statements (true or false). (a) \(n=4\) is the first excited state. (b) It takes more energy to ionize (remove) the electron from \(n=4\) than from the ground state. (c) The electron is farther from the nucleus (on average) in \(n=4\) than from the ground state. (d) The wavelength of light emitted when the electron drops from \(n=4\) to \(n=1\) is longer than that from \(n=4\) to \(n=2\). (e) The wavelength the atom absorbs in going from \(n=1\) to \(n=4\) is the same as that emitted as it goes from \(n=4\) to \(n=1\).
