What else can I help you with?
Is an electron and photon the same thing. It seems like my book interchanges them for one another. I'm confused?
No. The electron is not a photon. An electron is a charged particle of matter. A photon is a unit of "energy-time" designated by Planck's Constant h.
What are the difference between energy levels and energy states?
These terms are used to describe quantum particles like atoms. Energy level and energy state are used interchangeably, however, specifically energy level is used to describe physically where an electron is located in an atom and energy state describes the definite activity of the electron. Since the activity of an electron will dictate its location, this is where the terms become to mean nearly the same thing.
When an electron is passed to an electron acceptor molecule such as NADP what happens to NADP?
NADP becomes reduced to form NADPH when it accepts an electron from an electron donor, such as an electron. This reduction reaction allows NADP to carry high-energy electrons for use in cellular processes like photosynthesis.
What happens to an electron if it is given energy?
An electron emits energy in the form of an x-ray (a photon) when its energy level in the electron cloud decreases as a result of reduction in the excitation level of the cloud. This means that the position of the electron in the cloud changes to a lower level.
What are like shelves where electrons are found?
orbits are like energy levels where probability of finding electron is maximum
Why is it that sometimes when a very high energy electron hits a target material a positron and two or more electrons come out of the event?
An electron at high energy entering into a scattering event will bring all that energy with it. All that energy will have to be "dealt with" in the outcome. One way that a big chunk of it can be "handled" is almost magical. A large portion of the energy can be transformed into an electron-positron pair. This event is called pair production. We usually see it when a high energy gamma ray causes it, but it can be one of the outcomes in an energetic electron collision. The production of this pair of particles is the direct result of the conversion of energy into matter, and it will carry off a lot of the energy in the event. The minimum energy need to create the pair is 1.022 MeV. The original electron is still "in one piece" after the event, so it may look like the single electron crashed into a target and two electrons and a positron came away. It was actually the original electron and that electron-positron pair. If the original electron ionized another electron (or more) in the target material (which is possible), they will come away as well. Certainly there are a number of possible outcomes in an energetic electron scattering event, but pair production is one of the possible outcomes, depending on the energies involved and the target material.
What happens to energy when electrons transfer in electron cloud?
When electrons transfer within an electron cloud, energy can be released or absorbed depending on the nature of the transition. If an electron moves to a higher energy level, energy is absorbed, often in the form of light or heat. Conversely, when an electron falls to a lower energy level, energy is released, typically as electromagnetic radiation (such as photons). This process is fundamental to phenomena like chemical bonding and the emission of light in various materials.
What affects velocity of electron in the photoelectric effect?
The velocity of an electron in the photoelectric effect is primarily determined by the energy of the incident photon. If the photon energy is greater than the work function of the material, the electron can be ejected with higher velocity. Additionally, factors like the electric field in the material can influence the electron's velocity.
What is the difference between an electron shell and an orbital in an atom?
An electron shell is a group of electron orbitals at a similar energy level, while an orbital is the specific region within an electron shell where an electron is likely to be found. In simpler terms, electron shells are like floors in a building, and orbitals are like rooms on each floor where electrons can be located.
How does an electrons position in a n atom affect the energy it contains?
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
Is current return through the neutral?
yes but the load like any thing , the use of electron
Would an electron have to absorb or release energy to jump from the second energy level to the third level?
Electrons are attracted to the nucleus of the atom of which they are a part; this is because of the electrostatic force between the negatively charged electron and the positively charged nucleus. Therefore it takes energy in order to pull an electron farther away from the nucleus and to enable it to remain at a greater distance. This is exactly the same phenomenon as raising a heavy object such as, let us say, a bowling ball, to a greater elevation. It takes energy to do it, since you have to overcome the force of gravity.
