Where does nuclear energy exist in space?
Nuclear energy exists in space in the stars, such as our sun. Some of the satellites and probes we have launched also contain small nuclear power plants to generate their operating power. The existence of sites in Gabon, where critical mass was achieved naturally and natural fission reactions happened, in the distant past (2 billion years back, perhaps) indicate that fission reaction probably happen elsewhere in the universe. It is thought, however, that these are probably very uncommon.
How do matter and energy interact?
Matter and energy can convert into each other according to Einstein's famous equation, E = mc^2. This means that matter can be converted into energy and vice versa. For example, in nuclear reactions, some of the mass of the nucleons is converted into energy.
How mass can be converted into energy. give examples?
Mass can not be converted into energy. This is a common misconception. The example usually given is nuclear reactions. Note that this is no different from a chemical reaction, except that the energies involved (as well as the mass deficit, see below) are much greater in a nuclear reaction.Assume that hydrogen is fused into helium, in the Sun. Some would say that "mass is converted into energy". This is not true. The mass deficit (see: "mass deficit" article in Wikipedia for more details) means that the helium has less mass than the hydrogen. However, any energy leaving the place of the reaction - for example, light leaving the Sun - also has mass! If the energy stays there, say as heat, it contributes to the total mass! Thus, total mass is conserved.As to the energy, the light that leave the Sun has a certain energy. This energy is available before the reaction, as nuclear energy; a type of potential energy. Thus, total energy is also conserved.Since both mass and energy are conserved, there is no mass-to-energy conversion. The same happens for other nuclear reactions, or any reaction for that matter. Both mass and energy are always conserved.
Which source of energy is used for fusion?
Nuclear fusion produces energy from the changes in the nuclear composition of the fuel, which is a mixture of deuterium and tritium. Essentially what happens is that some of the mass of the nuclei is destroyed and this releases energy
Where energy is given off?
Energy is given off during exothermic reactions, where the system releases heat to the surroundings. Examples include combustion reactions, neutralization reactions, and some types of nuclear reactions.
A mass of gas in space made hot by nuclear reactions?
A 'proplid', or a proto-stellar object, often called a proto-star, and some believe (as I do) that 'Herbig-Haro Objects', are newly formed stars. At any rate, a star is a mass of gas in space made hot by nuclear reactions.
Is radium a source of nuclear energy?
Yes, radium is a radioactive element that can emit radiation and is used in some types of nuclear reactions to produce energy. It is not commonly used in nuclear power plants but has been used historically in early experiments to explore nuclear reactions.
Who was the first person to propose that in nuclear reaction some mass is converted into energy?
Albert Einstein was the first person to propose the mass-energy equivalence principle in his famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light. This laid the foundation for understanding how some mass can be converted into energy in nuclear reactions.

Why are the products of nuclear fusion slightly less massive than the reactions?
The products of nuclear fusion are slightly less massive than the mass of the reactants because some of the mass of the reactants is converted into nuclear binding energy to hold the fusion product together.
What is a toxic inert gas that is a product of some nuclear reactions?
Krypton-85 is a toxic inert gas that is a product of some nuclear reactions, especially nuclear fission. It is radioactive and can be a hazard to health if inhaled in large quantities.

All nuclear reactions due to nuclear transmutation?
Nuclear reactions may or may not involve nuclear transmutation. We need to split hairs here to arrive at the correct answer, and the answer involves the definition of the word transmutation. We sometimes think of transmutation as the changing of one element to another. Fission and fusion reactions do this, and many kinds of radioactive decay also convert one element into another. But there are some kinds of nuclear reactions that do not change an atom from one element to another, but instead change it from one isotope of a given element into another isotope of that element. There are a number of examples of this, and one is where isotopes of a given element absorb a neutron and become another isotope of that element. A given nucleus incorporates the neutron into its nuclear arrangement and the next heavier isotope of that element is created. If a "strict" definition of transmutation is used where it means a nuclear reaction that changes one element into another, then no, this does not always happen as illustrated above with the example of neutron absorption. If a more general interpretation of the term is used where we say that the nucleus transmutes meaning changes configuration, then yes, nuclear reactions involve nuclear transmutation.
