Is a hole a fundamental particle in an atom?
No a "hole" is not a particle, in solid state electronics a "hole" is a positively charged virtual charge carrier caused by the absence of an electron (which is a particle) from the atom's valence band. A "hole" has some properties making it act similar to a particle, but it is not one.
Who said that the location and velocity of an electron couldn't be known?
Werner Heisenberg proposed the uncertainty principle, which states that it is impossible to simultaneously know both the exact position and exact velocity of a particle, such as an electron. This principle is a fundamental concept in quantum mechanics.
Is the location of an electron in an atom best represented by a probability cloud?
Yes, the location of an electron in an atom is best represented by a probability cloud, which shows the likelihood of finding the electron in a particular region of space. This concept arises from the wave-particle duality of electrons in quantum mechanics. The probability cloud provides a more accurate description of the electron's position compared to a classic model of electrons orbiting a nucleus in fixed paths.
Which models of the atom reflects the unpredictable motion of the electron?
The Bohr model and the quantum mechanical model both reflect the unpredictable motion of the electron in an atom. The Bohr model introduced the concept of quantized energy levels for electrons, while the quantum mechanical model treats electrons as having both particle and wave-like properties, leading to uncertainty in their position and momentum.
How davisson and germer experiment confirms the wave nature of electron?
The Davisson and Germer experiment involved shining a beam of electrons at a crystal, which resulted in electron diffraction patterns similar to those of X-rays, confirming the wave-like behavior of electrons. This supported the wave-particle duality concept, which states that particles like electrons exhibit both wave and particle properties. This experiment provided strong evidence for the wave nature of electrons.
According to Louis de Broglie an electron is best represented by which of the following?
According to Louis de Broglie, an electron is best represented by a wave-particle duality, meaning that it exhibits both wave-like and particle-like properties. This concept is known as wave-particle duality.

When did Louis de broglie discover electron waves?
Louis de Broglie proposed the theory of electron waves in 1924 as part of his doctoral thesis, which suggested that electrons have both particle-like and wave-like properties. This marked a significant contribution to the development of quantum mechanics, laying the foundation for wave-particle duality and the concept of matter waves.
Who first wrote the electron waves equation that led to the mechanical model?
Erwin Schrodinger, a German physicist,
Who invented the electron?
Nobody "invented" the electron cloud. The concept was discovered by Werner Heisenberg in 1926.
The approximate distance an electron is located from the nucleus is measured by the?
The approximate distance an electron is located from the nucleus is measured by the concept of electron cloud or electron probability density. This concept is utilized in quantum mechanics to describe the distribution of the electron's probable locations within an atom.
What is the difference between rest mass and effective mass of electron?
The rest mass of an electron is its intrinsic mass at rest, which is approximately 9.11 x 10^-31 kg. The effective mass of an electron is a concept in solid-state physics that describes how an electron behaves in a crystalline solid as if it were a free particle with a different mass due to interactions with the crystal lattice. The effective mass can be different from the rest mass and varies depending on the material and the electron's energy level.
What scientist said that the position and speed of an electron is uncertain?
Werner Heisenberg developed the uncertainty principle, which states that it is impossible to measure simultaneously both the position and the momentum of a particle with absolute precision. This principle is a fundamental concept in quantum mechanics.
Is the location of an electron in an atom best represented by a probability cloud?

The probability cloud provides a more accurate description of the electron's position compared to a classic model of electrons orbiting a nucleus in fixed paths.
What is oxidation according to electronic concept?
loss of electron in electronegativity ion
Did niels Bohr come up with anything?
Niels Bohr (1885-1962) studied and adapted the works of Heisenberg, Planck, and others who investigated the particle and wave concepts of matter and energy. He was one of the earliest to work on quantum mechanics, which addressed the particle concept of energy. He disagreed with Einstein over the concept of the photon. Bohr developed the simplest concept of electron orbitals, where negatively-charged electrons circle a positively charged nucleus. His 1913 model defined energy states and the concept of electron energy levels (now defined by the quantum theory, electron clouds, and valence shells). He won the 1922 Nobel Prize in Physics.
