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 does the electron gun do in a crt monitor?
electron gun just fires electrons with certain energy so that when the electrons strikes on the pixels of the screen then they glow up with certain color... this color is defined according to the energy of electron..i.e electrons with high energy will lit up blue &with low energy lit up red color. energy=frequency*plank's constant(n)...
What is the incoming energy source for electron transport chain?
The electron transport chain is the driving energy behind ATP synthesis. The energy itself comes from electron donors. In chloroplast, this donor's glucose.
What happens to the energy of the electron as it falls down the electron transport chain?
pie
Do Solar Cells run out of electrons?
It won't run off. The Photo Voltaic create electron motion and the energy is tapped from the electron motion. The electron itself is not consume as energy but is the media energy would store. Picture hydropower, water evaporate to cloud and fall on high ground and the motion of water stream was tapped out to hydropower. Water is not depleted in the process because it is the kinetic and potential energy that water gain from sun in process of evaporation that is use.
Why do high-energy electrons need carrier molecules?
High-energy electrons are unstable and reactive, so they need carrier molecules to transport them safely without causing damage to the cell. Carrier molecules such as NADH and FADH2 can carry high-energy electrons during cellular respiration, allowing them to participate in energy-producing reactions without causing harm.
What happens when an electron moves from a low energy state to a high energy state?
When an electron moves from a low energy state to a high energy state, it absorbs energy. This absorption of energy causes the electron to jump to a higher energy level or orbit further away from the nucleus. The electron is now in an excited state and can later release this energy in the form of light when it returns to a lower energy state.
Does chlorine have a high electron affinity or a low ionization energy?
Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.
Why do potato chips have high energy levels?
Potato chips have high energy levels because they are deep-fried in oil, which increases their calorie content. They also contain a high amount of fat and carbohydrates, which are sources of energy for the body when consumed.
How does electron transport chain use the high energy electron from the Krebs cycle?
The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
What is the energ of he high energy elecrons used for every time 2 high energy electron move down the electron transport chain?

Name of high energy electron carriers in the electron transport chain?

What makes electron change from high energy to low energy?

Is atoms with high ionization energy allow their electrons to be easily taken?
No, atoms with high ionization energy require more energy to remove an electron, making it difficult for them to lose an electron easily. The ionization energy is a measure of the stability of an atom and its tendency to lose an electron.
What is a high energy electron from the nucleus called?
beta particle In beta decay a neutron is converted into a proton, electron (also called a beta particle) and an electron antineutrino.
