it becomes stable.
When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
Two less, since the alpha particle takes away two protons.
When a radioactive nucleus emits a gamma ray, it releases high-energy photons without changing its atomic number or mass. This emission helps the nucleus transition to a lower energy state, leading to greater stability.
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.

When U-235 emits a beta particle, it undergoes beta decay, transforming into Neptunium-235 (Np-235). During this process, a neutron in the nucleus of U-235 is converted into a proton, releasing a beta particle in the form of an electron and an antineutrino.
Alpha particle is the same as a helium-4 nucleus, i.e., two protons and two neutrons bound together. If an atom emits an alpha particle, it will have two protons less, and two neutrons less. Over time, there may be additional decay, which may further change the number of protons and neutrons.
The equation for the alpha decay of 210Po is:84210Po --> 82206Pb + 24He where He represents the alpha particle, which can also be viewed as a Helium nucleus.
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
