The collision of a positron and an electron is either a scattering event or a mutual annihilation event. Remember that the positron is antimatter; it's the antiparticle of the electron. It has a positive charge and will be attracted to electrons (or anything else negative). If a positron has extremely high energy, it will have to "slow down" before it and an electron can "mutually capture" each other and annihilate each other. Let's look at a positron with high kinetic energy that is moving very quickly through some medium like air or water. In scattering, the positron whizzes by an electron of an atom and some energy is exchanged. The positron will give a bit of energy to the electron, and how much will be determined by the energies of the positron and the electron, and some "probabilities" regarding the scattering, which could be either inelastic or elastic scattering. The net result is that the positron will leave the area moving a bit less rapidly. It lost energy (has less kinetic energy), and it is slowing down. As it slows, it experiences an increasing probability that it will be able to combine with an electron. The more it slows down, the more likely the "combining event" will become. When the positron "bumps into" an electron after slowing down, that positron and the electron will "combine" themselves, and all of their mass will be converted into energy. This energy will be carried off by a pair of electromagnetic rays, two gamma rays. And they'll have considerable energy and be moving in opposite directions. Conservation laws will have been upheld in the reaction. The combination of matter and antimatter results in mutual annihilation, and the two particles completely disappear, having had all of their mass converted into energy.
What else can I help you with?
What happens to ionic radius if you add an electron?
Adding an electron to an atom increases its negative charge, leading to an increase in electron-electron repulsions. This results in the outer electron shell expanding, causing the ionic radius to increase.
A lithium atom that has lost an electron it comes near a Chlorine atom that has gained an electron what happens?
They form an ionic compound
What happens to the atomic radius when an electron is gained?
The negative ionic radius is larger than the neutral atomic radius
What happens when cesium form its ion?
When cesium forms an ion, it loses one electron to become Cs+ with a full outer electron shell. This results in the formation of a cation with a positive charge due to the loss of one electron.
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.
Describe what happens when a positron and an electron collide?
They destroy each other and create a gamma photon.
What happens to the energy of a vibrating electron that does not collide with neighboring atoms?
The energy of a vibrating electron that does not collide with neighboring atoms can dissipate as electromagnetic radiation in the form of photons. This process is known as spontaneous emission. The electron can also transfer its energy to nearby electrons through a process called resonant energy transfer.
What happens when a positron and a electron collide?
When a positron and an electron collide, they annihilate each other and produce gamma rays. This process is known as electron-positron annihilation. The total energy of the particles is converted into electromagnetic energy in the form of gamma rays.
What happens when two photons collide with each other?
When two photons collide with each other, they can either scatter off in different directions or combine to create new particles, such as an electron and a positron. This process is known as pair production.
What happens when continets collide?
it makes an Earthquake
What happens when to tectonics plate collide?
an earthquake
How do you explain What Happens When continents Collide?
when continents collide you bum your pet hamster
What happens when dark and normal matter collide?
A collision.
Can you explain why an electron's energy increases when it absorbs a photon and also describe what happens to the photon in this process?
When an electron absorbs a photon, its energy increases because the photon transfers its energy to the electron. The photon ceases to exist as a discrete particle and its energy is absorbed by the electron, causing it to move to a higher energy level.
What happens when two contients collide?
Earthquakes and mountain building.
What happens when plates collide into each other?
It creates mountians
What happens when 2 land plates collide?
it makes a mountain
