Both a star's diameter and its radiation vary widely from one star to another. Look at the data for our Sun, for an example - but consider that this is not exactly typical, in the sense that other stars can be much bigger or smaller, and radiate much more, or much less, energy, than our Sun.
diameter is from on side to the end and radiation is half of the diameter.
Long wavelength radiation given out by stars is typically in the form of infrared radiation. This type of radiation has longer wavelengths than visible light and is emitted by stars as a product of their high temperatures. It is important for studying the properties and evolution of stars.
That sounds like the description of a quasar. Those are related to active supermassive black holes.
If it is not stable, then the atom will likely either emit alpha radiation or beta radiation in order to become more stable.
The stable nitrogen doesn't emit any radiation.
There are huge variations in a star's diameter. Our Sun has a diameter of about 1.4 million kilometers, but a few stars have hundreds of times this diameter - and of course, some stars are smaller than our Sun. It is hard to say what is "normal" with such huge variations, but probably the majority of stars are a little smaller than our Sun.There are huge variations in a star's diameter.

Yes, an isotope can exist that emits no radiation if it is stable. Stable isotopes do not undergo radioactive decay, which means they do not emit radiation over time. For example, carbon-12 and carbon-13 are stable isotopes of carbon that do not emit radiation, while carbon-14 is a radioactive isotope that does emit radiation as it decays.
Stars can emit various forms of radiation, including ultraviolet, X-rays, and gamma rays. Sun-like stars emit primarily visible light and some ultraviolet radiation. More massive stars can also emit X-rays and gamma rays.
The atoms are stable when having the ratio of neutrons to protons that lie on the atom stability line. These stable atoms do not emit radiation as alpha, beta, neutron, or gamma radiation.
Not on the Earth.
