What else can I help you with?
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.
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.
What is an antiproton?
An anti-proton is a particle, the opposite of a proton. In theory every particle has an anti-particle and if a particle collides with it's anti-particle they wll both be destroyed and a large amount of energy will be released. Anti-protons were first made in a laboratory in 1955, and are routinely made in high energy particle accelerators today.
What is positron capture?
The decay of an unstable atom by absorbing a wandering positron into the nucleus, converting a neutron into a proton. One example is how a radioactive form of iodine, 131I, can use positron capture to become xenon, 131Xe. This is a stable, so the conversion is a big help.
How does positron emission cause nuclear transmutation?
It is in beta plus decay that we see the positron emitted from the nucleus. (An electron is emitted in beta minus decay.) Within the nucleus of an unstable atom, a proton transforms into a neutron, and a positron is ejected from the nucleus (along with a neutrino). As the nucleus now has one more proton than it did before, its atomic number just went up by one; it is another element.
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.
A positron orbiting an antiprotron would make up an atom of?
Anti hydrogen , antimetter.
What is anti hydrogen?
Antihydrogen is a form of antimatter consisting of an antiproton and a positron (antielectron). When antihydrogen comes into contact with ordinary matter, they annihilate each other, releasing energy in the form of gamma rays. Scientists study antihydrogen to better understand the nature of antimatter and its interactions with ordinary matter.
Where would you find an electron?
Orbiting or circling an atom
What is a discovered particle belongs to antimatter?
Read the book The atom and The universe: Theories and Facts unfold, published by www.Xlibris.com
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.
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.
