In Beta decay, a neutron changes into a proton and an electron. Overall charge is conserved, but as the electron is flung out of the atom, there is positive charge left in the atom.
The mass number is the same because an electron's mass is so tiny compared to a proton or a neutron.
Beta decay is a process whereby a nucleus emits either an energetic electron and an anti neutrino or a positron (a positively charged electron or the anti particle of the electron) and a neutrino. The decay processes are notated: -
(A)XZ -> (A)X(Z+1) +e(-) + ν'
or
(A)XZ -> (A)X(Z-1) + e(+) + ν
Where 'X' is the nucleus undergoing a beta decay, with 'A' the mass number or sum of protons and neutrons, and 'Z' the proton number or nuclear charge.
These decay processes are mediated by the weak nuclear force. In electron beta decay a neutron decays into an electron and an anti neutrino and so converts into a proton with a nett nuclear charge gain of Z+1 but because the mass number A is the sum of neutrons and protons its value remains the same. In positron beta decay, an inner most electron is captured and a proton converts into a neutron with a nett nuclear charge change of Z-1 with again no overall change in the sum A of neutrons and protons.
Beta decay happens when a neutron in a nucleus turns into a positron and an electron. The electron is shot out of the nucleus so fast that there is no way it can stay attached to the atom/ion. This leaves a positively charged ion.
There is no change in mass number because that is worked out by adding the number of protons and neutrons in a nucleus. Since there is one more proton and one less neutron this is the same.
There is a minute change in mass, but the mass of the electron (and the energy given to it) is almost nothing compared to the mass of protons and neutrons so you don't really need to think about it.
Beta decay caused the radioactive element to lose one electron. This causes the number of electrons in the atom to decrease by one thus the atom gets a unit of postive charge.
There is no change in mass number as the mass of an electron is very small compared to that of an neutron or a proton so its negligible.
if a molecule lose one of its electron the molecule is need another electron to get back to its state before(particle that need electron is called--positive particle)
in a normal condition a particle have same number of proton and electrone so it could be called neutral.
then if an atom lose its electron it would be a positive particle

beta ray is just the same with electron
if a molecule lose one of its electron the molecule is need another electron to get back to its state before(particle that need electron is called--positive particle)
in a normal condition a particle have same number of proton and electrone so it could be called neutral.
then if an atom lose its electron it would be a positive particle
