The equation for the beta decay of 3H is:
13H --> 23He + -10e
where -10e represents a negative beta particle or electron.
There are 3 naturally occurring isotopes of Uranium, all decay by alpha to Thorium:238U --> 234Th + 4He235U --> 231Th + 4He234U --> 230Th + 4He
The isotope of hydrogen we call tritium is radioactive because all atoms of it have an unstable nucleus. Tritium, which is hydrogen-3, has a single proton in its nucleus (as you'd expect), and has two neutrons there as well. This combination of nucleons is not stable, and it will eventually decay (with a 12.32 year half-life). Said another way, the nuclear arrangement of a proton and two neutrons is not a stable one, so atoms of this isotope of hydrogen will be radioactive and will eventually decay. When any atom is "created" by fusion or other means (including nuclear decay), the nucleons (the protons and neutrons that make up its nucleus) have to "make a deal" as to how they are going to get along in the tiny volume of space that the nucleus occupies. Some arrangements of protons and neutrons just "aren't right" and are unstable, and this gives rise to characterizing the isotope as being radioactive. Tritium (H-3) is one such isotope.
Nitrogen, according to the equation: N2 + 3 H2 -> 2 NH3.

The only hydrogen isotope that undergoes any type of radioactive decay is tritium (hydrogen-3), it undergoes beta decay to become helium-3. If that's not what you were asking about, I'm confused by your question.
Alpha, Beta, and Gamma

beta, aka an electron.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
In order for an atom of an element that is not radioactive to become radioactive, the isotope has to change. This can happen as a result of neutron capture. Neutron capture can simply change the isotope of an atom, as when cobalt-59, which is not radioactive, captures a neutron to become cobalt-60, which is radioactive. Neutron capture can also result in immediate radioactive decay of the atom struck, even if it is not radioactive. For example helium-3 can capture a neutron to produce two atoms of hydrogen, one of hydrogen-3 and one of hydrogen-1.
The word equation for ammonia is 3 H2 + N2 → 2 NH3 (this is a balance equation) The formula (atom) is NH3 for ammonia

The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
Nuclear decay does not require an initiating event. The instability of of the nucleus causes random decay. This is a result of the fact that the nuclear force (residual binding energy) in larger nuclei starts to be overwhelmed by the electromagnetic force because the nuclear force decreases at a greater rate with subatomic distance than does the electromagnetic force. The nuclear force is an attractive force, while the electromagnetic force, for protons, is a repulsive force, but initially, the nuclear force is nearly 100 times more powerful than the electromagnetic force. At a certain point, specifically around atomic number 83, Bismuth, the nucleus starts to become unstable.On the other hand, if you are asking about nuclear fission, as opposed to nuclear decay, that process is often initiated by the absorption of a neutron, which further destabilizes the nucleus, causing it to split, usually in a 2:3 ratio. The exception is that some isotopes do decay by spontaneous fission.
