What is the change in atomic number when an atom emits a positron?

Emitting a positron, turns a proton into a neutron. So the atomic number goes down by 1, while the mass number remains the same.


Do all electrons orbit the nucleus of an atom at the same level?

No, the electrons orbiting an atom have multiple levels.


Is there a positron in the nucleus of an atom?

There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.


What is an atom name that is made of a proton a neutron and an electron?

It is the atom of deuterium. Its nucleus is composed of a proton and one neutron. The atom has one electron that is orbiting around the nucleus.


Why don't positrons annihilate the electrons in the same atom when they're released?

The positron released from an atomic nucleus in positron emission (or beta plus decay) appears with high kinetic energy. It's moving very quickly, and because it is, it has an extremely low probability of actually interacting with that atom's electrons in mutual annihilation. That positron will undergo some scattering events to dump energy, and only then will the probability of it being able to actually "combine" with an electron increase to the point where it will actually do so.

What would a positron orbiting an antiproton make up an atom of?

A positron orbiting an antiproton would make up an exotic atom called positronium. Positronium consists of an electron-like particle (the positron) and a proton-like particle (the antiproton) bound together by electromagnetic forces. It has a short lifespan before annihilation occurs, releasing gamma-ray photons.


Where would you find an electron?

Orbiting or circling an atom


In an atom of antimatter what would be the charge of an electron?

An atom of antimatter does not contain any electrons. The equivalent of an electron in antimatter is a positron, which has charge +1.


Where does the positron produced during positron emission come from?

In positron emission, the positron is produced from the nucleus of an atom when a proton is converted into a neutron and a positively charged positron. This process helps to make the nucleus more stable by decreasing the number of protons.


Positrons orbiting antiprotons would make up an atom of?

If you have one antiproton and one anti-electron, you would have an atom of anti-hydrogen.


How many orbiting electrons in germanium atom?

A germanium atom has 32 electrons orbiting around its nucleus.


What are the three particles in an atom and what charge they do have?

electron,neutron,positron


An excited atom can lose energy by?

An excited atom can lose energy by emitting a photon of light, a process known as spontaneous emission. This photon carries away the excess energy, allowing the atom to return to a lower energy state.


What is orbiting the outside of an atom?

Electrons orbit the nucleus of an atom.


How do positron emission and electron capture change an atom?

Positron emission results in the atom losing a proton, transforming the atom into a different element with a lower atomic number. Electron capture involves the atom gaining a proton, resulting in the transformation of the atom into a different element with a higher atomic number. Both processes lead to the formation of a more stable nucleus by adjusting the ratio of protons and neutrons.


What are the differences between a positron and a proton?

A positron is the antimatter counterpart of an electron, with a positive charge, while a proton is a subatomic particle found in the nucleus of an atom, with a positive charge.


The number of electrons orbiting an atom usually equals the number of protons in the nucleus of an atom?

Yes, the number of electrons orbiting an atom is typically equal to the number of protons in the nucleus. This balance is essential for an atom to be electrically neutral.
