In physics what is an electron volt?
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
When electrons move closer to the nucleus is energy lost or gained?
The electron decreases energy when it comes nearer to the nucleus.
How does heat generate light?
Heat is the amount of energy a single atom has, and this energy causes the electrons in an atom to change energy levels. The light is produced when an "excited" electron has gained enough energy to raise to a higher level via heat, and then falls back to a lower energy level, releasing the energy as light. The higher the amount of energy put into an atom via heat, the more intense the light will be due to a higher release of energy.
What energy type is generated by nuclear energy?
Nuclear decay produces energy that can be regarded either as kinetic energy or as heat. It is measured in electron volts. If that is confusing, the confusion arises from the fact that we are operating at the atomic level, which most people never have the opportunity to observe. Heat is actually the amount of energy in atoms as they move about in space. It is related to the speed of the atoms, which is kinetic energy. We do not get a sense of this because at our level, the atoms are not observable, and since their motion is random, and there is an immense number of them, they cannot move objects in any way we can observe visually or by feel. We observe is the excitation as heat. An electron volt is not a unit of electricity, but a unit of kinetic energy. It is the amount of energy gained by an electron accelerated through an electric potential difference of one volt. It is the difference of energy caused by a difference in speed.
Does energy lost equal energy gained?
no
What is an electron vault?
1 electron-volt is a small unit of energy. It's the amount of energy gained or lost by the (amount of electric charge on one electron) moving through a (potential difference of one volt). 1 joule of energy is the same as about 6,241,400,000,000,000,000 electron-volts.

When electrons move closer to the nucleus is energy lost or gained?

What happens when chlorine atoms gain an electron in its outer energy shell?
what happen when an atom what has a lot of electron comes in contact with an atom that has gained an electron
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
Energy is gained or lost by atoms in an amount called what?
You think to quanta.
What does an atom that has lost or gained an electron become?
Generically an "ion", specifically gained an electron an "anion", lost and electron a "cation".
How light generate heat?

When is energy gained and when is it lost?
In olden days scientists considered energy to flow continuously and so any amount of fraction is possible. But Planck imagined in a revolutionary way that energy is not coming out or getting absorbed continuously but only in small packets. That packet is named as quanta which has energy given by hv, here h is Planck's constant and v is the frequency of radiation. So 1/2 hv is not possible but n * hv where n is an integer.
How atoms and molecules can gain or lose energy in discrete amount?
The enrgy is always lost or gained in only the definite amount that is called as discrete or packet energy.
How many watts equals 1 million electron volts?
1 million electron-volts = roughly 4.45 watt-hours.By definition, 1 electron-volt is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electric potential difference of one volt.The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.
