What is the difference between free electron theory and nearly free electron theory?
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
How does energy remain constant during free fall?
Let's assume the object is falling down (this is only one case of free fall). Its speed increases, therefore, its kinetic energy increases. However, to compensate, the object loses energy of position - potential energy. The sum of the two, kinetic energy + potential energy, remains constant, as long as no other forces (other than gravity) act on the object.
Is it possible to have more kinetic energy than potential energy?
Yes, it is possible to have more kinetic energy than potential energy. Kinetic energy is associated with the motion of an object, while potential energy is associated with its position or state. For example, in free fall, an object has maximum kinetic energy and minimal potential energy at the bottom of its trajectory.
The term for free electrons in metals transferring energy by colliding with other atoms or electrons?
The term is "electron diffusion." In metals, free electrons can transfer energy through collisions with other atoms or electrons, leading to a net movement of charge known as electron diffusion.
Energy conservation during free-fall?
During free-fall, potential energy is converted into kinetic energy as an object falls due to gravity. This conversion process is an example of energy conservation, where the total mechanical energy (potential energy + kinetic energy) of the object remains constant throughout the fall in the absence of external forces like air resistance.
What is the change of energy called as it moves between kinetic energy and potential energy and back again?
The change of energy as it moves between kinetic and potential energy is called mechanical energy. This occurs in systems where the total mechanical energy (kinetic + potential) remains constant, such as in the case of an object in free fall or a swinging pendulum.

Can free electron absorb photon?
Yes, free electrons can absorb photons. When a photon interacts with a free electron, it can transfer its energy to the electron, causing it to move to a higher energy level or even be ejected from the material. This process is the basis for various phenomena such as photoelectric effect and Compton scattering.
Why does aluminum conduct?
Because it has a free electron in the conduction energy band.
What is the relationship between chemical potential and Gibbs free energy in a chemical system?
In a chemical system, the chemical potential is related to the Gibbs free energy. The chemical potential represents the energy required to add one molecule of a substance to the system, while the Gibbs free energy is a measure of the system's overall energy available to do work. The relationship between the two is that the change in Gibbs free energy of a reaction is related to the change in chemical potential of the reactants and products involved in the reaction.
What is Relationship between redox-potential and free energy?
The relationship between redox potential and free energy is that redox potential is a measure of the tendency of a molecule to lose or gain electrons, which relates to the change in free energy associated with the redox reaction. A more positive redox potential indicates a greater tendency to lose electrons and a more negative redox potential indicates a greater tendency to gain electrons, reflecting the spontaneity of the redox reaction and the associated change in free energy.
Why does aluminum conduct electricity?
Because it has a free electron in the conduction energy band.
What is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
The merging of a free electron and a hole is called?
The merging of a free electron and a hole is called recombination. This process occurs in semiconductors when an electron fills a hole in the valence band, resulting in the release of energy in the form of light.
Which electron in oxygen have the higher energy those in the first energy level or those in the second?
The second level is associated with higher energy than the first is. Keep increasing the energy of an electron enough, and eventually it breaks free of the atom completely.
What is free electron?
A free electron is an electron that is not bound to an atom or molecule and is free to move independently. These electrons contribute to the electrical conductivity of materials like metals. In metals, some of the electrons in the outer energy levels of the atoms are not tightly bound and can move freely throughout the material.
