Who developed the model of the hydrogen atom?
In a sense Niels Bohr did by introducing different orbits in which electrons spin around the nucleus. Bohr argued that each electron has a certain fixed amount of energy, which corresponds to its fixed orbit. Therefore, when an electron absorbs energy, it jumps to the next higher orbit rather than moving continuously between orbits. The characteristic of electrons having fixed energy quantities (quanta) is also known as the quantum theory of the atom.
What is the contributions of sir isaac newton in quantum theory?
None. There was no quantum theory in Newton's time. That came obou more than 150 years later.
Was quantum theory tested?
Quantum theory has been tested and theoretical and experimental values have been found to agree to more digits of precision than in any other theory tested against reality!
What are thee different theories of light?
Newton's corpuscular theory Huygen's mechanical wave theory Maxwell's electromagnetic wave theory Finally Planck's quantum theory LIght as a single "photon" acts somewhat differently than a wave (of energy).
How important were Niels Bohr's discoveries?
Niels Henrik David Bohr was a Danish philosopher, scientific research promoter and a physicist that was born on October 7, 1885. He had a great contribution in atomic theory because he is the one who made the foundation contributions to understand the quantum theory and atomic structure, and because of that he received the 1922 Nobel Prize in Physics.
What is the difference between quantum physics and metaphysics?
Metaphysics is more of a philosophical theory rather than a mathematical one like quantum physics.
Why is bohr's theory incorrect?
The Bohr's atom model is still used because of its simplicity, and its correct results for selected systems. The Bohr model is still taught to introduce students to quantum mechanics or energy level diagrams.
What is quantum theory?
Quantum theory is the mathematical representation of the universe assuming that everything is divided into well defined amounts (quanta, plural of quantum if we ignore the context) that behave both like particles and waves.One of its basic concepts is that nothing is in one defined position but exists as a distribution of probabilities dispersed in space. The particle itself may react at any point, but it has different probabilities of "appearing" at different positions.Another characteristic of Quantum Theory is that in it, whatever you cannot measure can be in an infinite different amount of states. The actual state you see when you you finally observe the system depends, not only on what you observe, but also on how you observe it.-----Quantum theory is the language of all particle theories. It is formulated in a well-defined mathematical language that makes predictions for the relative probabilities of the various possible outcomes, but not for which outcome will occur in any given case.The word quantum means a definite but small amount.The basic quantum constant h, known as Planck's constant,and its value is 6.626 x 10-34 JsThe quantum theory of physics was developed in order to explain the relationship between matter and energy at an atomic level as well as subatomic. The theory was created by the ideas of Max Planck, Albert Einstein, Niels Bohr, Werner, and many others. It includes basic ideas of quantum physics. One of the most prominent ideas is that matter acts as waves AND as a particle (wave-particle duality). Another crucial idea to the theory is the uncertainty principle. This principle states that certain pairs of values about matter cannot be simultaneously known. For example, if the position of a particle is measured, its momentum value will become less accurate.At its simplest - it states that the universe is grainy, that energy (like matter) comes in discrete packets rather than being continuous (as it seems to be).
Who discovered that electrons go around the nucleus of an atom on energy levels?
Ernest Rutherford created the model of the atom with electrons orbiting the nucleus, Werner Heisenberg added the energy levels using his theory of Quantum Mechanics to explain why those electrons don't instantly spiral into the nucleus emitting x-rays and gamma rays destroying all atoms.
Why do some chemists preferred Lewis model of the atom to Bohr model?
scientists think the electron cloud theory is more acurate because the electrons are not like the solar system. they dont have a certain position(bohr theory0 but go around in all different dirrections forming a cloud.
How did Bohr propose the particles within the atom are arranged?
Bohr built upon the contemporary theory and models such as those of Rutherford and proposed an atomic model with most of the atom's mass concentrated in the center (later referred to as the nucleus) and electrons around the center arranged in orbits in discrete positions or energy levels; this explained some experimental findings consistent with emerging quantum theory.
How did Niels Bohr overcome the problem with the Rutherford Model of the Atom?
"Epistemology, or, "theory of knowledge", is the branch of philosophy that studies the nature, methods, limitations and validity of knowledge and belief. (Wilkipedia Epistemology) According to Plato, and, represented by a figure of subsets, knowledge is the subset of what is both true and believed. Epistemology was the basis for "debates" between Albert Einstein and Niels Bohr on quantum physics and many more topics. Actually close friends, Einstein and Bohr discussed not only quantum physics, but many more topics, taking the form of an Einstein challenge and a Bohr response; discussions rather than debates which yielded a lot of information. (Wilkipedia Bohr-Einstein debates) Niels Henrik David Bohr, (October 7, 1885-November 18, 1962), "...a Danish physicist who made fundamental contributions to understanding atomic structure and quantum physics..." (Wilkipedia Niels Bohr) Bohr basically was considered the father of atomic structure. (Hart Page 512) Bohr sharpened his thinking studying with J.J. Thompson who discovered the electron. Further He studied with Ernest Rutherford who discovered the atomic nucleus. Bohr developed his own theory which was published in 1913 as an epoch-making work "On the Constitution of Atoms and Molecules". (Hart page 512) Bohr described an atom as a miniature solar system with electrons revolving around the heavy nucleus. (Hart page 513) Bohr's work did a lot of explaining regarding the structure of the atom, including the explanation as to why it was limited in size; and, the fact that light did not include all colors. Additionally, Bohr predicted the existence of additional spectral lines and, ultimately won the Nobel Prize in Physics in 1922.
