The electron emitted in β-radiation originates from where?
- A
Inner orbits of atoms
- B
Free electrons existing in nuclei
- C
The decay of a neutron in a nuclei
- D
Photon escaping from a nuclei
Beta radiation is a type of ionizing radiation emitted by certain radioactive nuclei. It consists of high-energy electrons (beta particles) that are emitted from the nucleus during a process called beta decay. The electron emitted in B-radiation does not originate from a specific location within the atom. Instead, it is created during the decay process when a neutron is converted into a proton and an electron. The electron is then ejected from the nucleus with high kinetic energy, making it a beta particle
For Example:
This option is incorrect. Inner orbits of atoms: Electrons in the inner orbits of atoms are not related to beta radiation. Beta radiation comes from the nucleus.
This option is incorrect. Free electrons existing in nuclei: There are no free electrons in the nucleus. The nucleus contains protons and neutrons.

This option is incorrect. Photon escaping from a nuclei: Photons are emitted in gamma radiation, not beta radiation.
