a proton and an electron
Neutron emission is typically related to fission, but they can also be released by themselves in certain cases where there is a excess of neutrons, such as beryllium-13 and lithium-10.
neutron emission
It changes only the atomic mass.
In beta radiation, an emission of electrons can occur due to beta decay. A neutron can disintegrate into protons and electrons.
In beta decay, the nucleus of the atom emits an electron. This is a new electron, not one of the electrons in the electron cloud. This does indeed have the effect of changing a neutron into a proton, because total charge has to be conserved - if a new negative thing exists, there has to be a new positive thing too. But the mass has to stay the same too - conveniently, protons and neutrons have almost the same mass.
Beta- decay involves changing a neutron into a proton, with the emission of a W- boson, said boson then decaying into a electron and an electron antineutrino. Beta+ decay involves changing a proton into a neutron, with the contribution of energy, and then the emission of a positron and an electron neutrino.
Technically they are two totally different particles. That being said, in beta emission a neutron is converted into a proton and an electron is released.
No, not all radiation is electromagnetic radiation, though some is. Exceptions: Neutron radiation - Emission of neutrons. Alpha decay - Emission of a helium-4 nucleus (2 protons and 2 neutrons). Beta radiation - Emission of electrons.
Radio active isotopes are unstable isotopes of an element as there neutron number degenerate by emission of light or medium.
Xenon-135 decay to caesium-135 by beta emission.
There are two types of beta decay: B- decay, and B+ decay. B- decay results in the emission of an electron (e-), while B+ decay results in the emission of a positron (e+). . B- decay occurs when the neutron in the nucleus of an atom converts into a proton and an electron. The resulting proton remains in the nucleus, while the electron is ejected form the nucleus, sometimes at high speed. This process releases energy, and therefore can occur spontaneously. . B+ decay occurs when energy is applied to a proton, and the resulting interaction causes the proton to convert into a neutron and a positron. The neutron remains captured in the nucleus, while the positron is ejected, sometimes at high speed. Note that B+ decay cannot occur spontaneously - it requires energy, usually in the form of a high speed colission with another particle.
