Radioactive isotopes release energy in the form of heat as they break down.
Heat itself increases the rate of this break down.
Because the isotopes do not appear in equal amounts. This is hardly surprising since many isotopes experience radioactive decay and change to other elements after decay while stable isotopes persist - thus stable isotopes will usually dominate as the most common isotopes for individual elements with those with the longest half-lifes being more common than those with shorter half-lifes. Of course when you get into the heaviest elements there don't seem to be any stable isotopes so those with longest half life dominate.
You add or remove one or more neutrons from each atom.
The atomic number of isotopes of the same element is the same because they all have the same number of protons in their nucleus. The mass number of isotopes, however, can vary because it is the sum of protons and neutrons in the nucleus, and different isotopes can have different numbers of neutrons.
Protons basically determine what type of element you end up with. All you really have to do is add or subtract protons and you will end up with a completely different element. Also removing or adding specific numbers of neutrons can result in radioactive isotopes of that element.
Add heat.
All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive.Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay.radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.

Add heat.
No energy, no heat. So you cannot add heat.
Solid iron and nickel at the inner core, due to the Pressure. And surrounded by the outer core, which with less pressure is liquid, but at essentially the same temperature - about 5700 K. Many of the heavy minerals here are radioactive, hence the internal heat, though gravitational compression will add a little heat as well.

and add it to water
Alloys can add heat resistance to a metal
No. It takes heat from the environment.
