Carbon-14 decays to Nitrogen-14 by beta- decay with a half-life of 5730 years ...
614C --> 714N + (W- --> e- + v-e)
... which means that a down quark is converted to an up quark by the weak interaction, converting a neutron into a proton and emitting a W- boson, which then subsequently decays into an electron and an electron antineutrino.
When C-14 emits its beta particle (electron), one of the neutrons becomes a proton, which keeps your mass constant, but increases your atomic number by one. So now, you have stable nitrogen-14. This is a big part of the reason why our atmosphere is so nitrogen-rich.
"Beta decay" may either refer to an atom emitting an electron, or an anti-electron (positron). In the case of carbon-14, it emits a negative electron, and becomes nitrogen-14. Note that the number of nucleons (14) remains the same, the number of protons increased by one (from 6 to 7), and the number of neutrons decreased by one.
the aTOM of protactinium 234 formed
This isotope is nitrogen-14.
gamma radiation!
Yes, plutonium-239 emits alpha particles by decay.
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
When 60Co decays by beta- decay it produces 60Ni.
90 protons left
Helium
3he
This isotope is radium-226.
The resulting element is protactinium, atomic number 91.
Emitting an alpha particle 213Bi become 209Tl.
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
When a beta particle is emitted a neutron changes to a proton in the nucleus. Thus the molecule would have one more proton, so would be an isotope of nitrogen.

dude..
This is a radioactive isotope.
