Difference between beta particle and electron

Key difference - beta particle vs. electron

Beta particles are the subatomic particles that are emitted during beta decay . Beta particles can be either electrons or positrons . If it is an electron, that beta particle has a negative electrical charge, but if it is a positron, it has a positive electrical charge. Electrons are subatomic particles that are located in the electron cloud that surrounds the atomic nucleus. The main difference between beta particles and electrons is that beta particles can either have a +1 charge or a -1 charge, while an electron has a -1 charge.

Difference Between Ion Beta Particle and Electron - Comparative Summary

What is a beta particle?

A beta particle is a high-energy, high-speed electron or positron that is emitted when the beta decays. It is denoted by the symbol "β". Beta particles are emitted during the radioactive decay of an unstable atomic nucleus. There are two types of beta particles as β + particle or positron and β - particle or electron.

β - decay is also known as electron emission, since β - particle is an electron. This type of radioactive decay occurs in unstable nuclei with an excess of neutrons . Here the conversion of a neutron into a proton and an electron takes place. With this type of decay, the atomic mass does not change, but the atomic number does.

The Β + decay is also known as positron emission, since a β + particle is a positron. This type of decay occurs in atomic nuclei with an excess of protons. A proton is converted into a neutron and a positron. In this type of decay, the atomic number changes, but not the atomic mass.

Beta radiation is a type of ionizing radiation. Beta particles have moderate penetration when beta radiation is directed at a substance. The ionization strength is also medium up to that of alpha and gamma rays . The ionizing energy of beta rays arises from the presence of charged particles (electrons are negatively charged; positrons are positively charged).

Beta particles have medical uses. Beta particles are used to treat eye and bone cancers. In addition, beta particles or beta radiation are used to determine the thickness of a fabric such as paper. The positron decay of a radioactive tracer isotope is the source of positrons used in PET (positron emission topography).

What is an electron

Electron is a subatomic particle that has a negative electrical charge. Electrons are known to be in the electron cloud that surrounds the atomic nucleus, and these particles move in certain paths known as electron shells. There is a high probability of finding an electron near the atomic nucleus. However, there are no electrons in the atomic nucleus. The electron is denoted by e - or β - .

The electric charge of an electron is -1.6022 x 10 -19 C and the mass of an electron is 9.1094 x 10 -28 g. The mass of the electron (g is the mass of both particles 1.6740 x 10 -24, and therefore the mass of an electron is only 1 / 1,836 of the mass of a proton) as compared to the mass of a proton and a neutron negligible. But the atomic charge of an electron is given as -1 and the atomic mass as 0.00054858 amu.

The electron was discovered by Sir JJ Thomson. According to the standard model of particle physics, electrons belong to the group of subatomic particles, the so-called leptons. It is believed that leptons are the elementary particles. Electrons have the lowest mass among other leptons

Difference between beta particle and electron

definition

Beta particle: A beta particle is a high-energy, high-speed electron or positron that is emitted when the beta decays.

Beta particles can be either electrons or positrons. These particles come from atomic nuclei during beta decay. Electrons are already in the atoms that surround the atomic nucleus (in an electron cloud). The main difference between beta particles and electrons is that beta particles can either have a +1 charge or a -1 charge, while an electron has a -1 charge.
