Do all electrons orbit the nucleus of an atom at the same level?
No, the electrons orbiting an atom have multiple levels.
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.
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?
It would make an atom of anti-hydrogen-1. Anti-hydrogen has been manufactured in labs using particle accelerators.
An excited atom can lose energy by?
*Capturing an orbiting electron *Emitting a positron So C both of the above
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 would you find an electron?
Orbiting or circling an atom
What would you find orbiting the nucleus of an atom?
If you're referring to the nucleus of an atom, the answer is electrons.
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 do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
What are the three particles in an atom and what charge they do have?
electron,neutron,positron
If an atom losses an electron it will be positive and called a what?
It will be called as positron.
What is orbiting the outside of an atom?
Electrons orbit the nucleus of an atom.
What is orbiting around an atom?
A cloud of electrons orbit an atom and its nucleus.
When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.
