beta particle
A beta particle is a negative electron. A positive electron is a Positron.
A beta particle is an electron or a positron emitted from an unstable nucleus during beta decay. Beta decay occurs when a neutron in the nucleus changes into a proton and emits either an electron (beta minus decay) or a positron (beta plus decay) to achieve a more stable configuration.

The electron has the speed of light.
The speed of an electron in its orbit around the nucleus is approximately 2.18 million meters per second.
Beta minus radiation is a stream of electrons.
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.

Electrons move fast around the nucleus at speeds close to the speed of light. The exact speed of an electron is determined by its energy level and its distance from the nucleus.
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
Electrons are located outside the nucleus revolving around. These electrons may be named as Chemistry electrons. But when neutron within the nucleus decay, then proton and electron are produced. This electron was not already there in the nucleus. But only due to decay of neutron electron comes out. This electron may be named as Physics electron. This electron comes out at very speed and this is sensed as beta particle, named by Henry Becquerel.
