A reaction in which small nuclei combine to form a heavier nucleus?
That is nuclear fission. An example is that of a Uranium-239 atom undergoing beta decay. That is, a neutron in the nucleus ejects and electron, becoming a proton, resulting in Uranium-239 becoming Neptunium-239.
What particle of the atom is responsible for the nuclear reaction?
The protons! If a proton is removed from an atom it fission (usually from Uranium) and if one is gained it is fusion.
What is nuclear fusion reaction of stars?
Hydrogen atoms react to form a helium atom at 14.10e6 K.
Fission and fusion is an example of what kind of energy?
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
What separates a chemical reaction from a nuclear reaction?
In a nuclear reaction, the nucleus of an atom undergoes a change. Common examples would be alpha decay, beta decay, fusion, and fusion. In each of those cases, different elements are formed in the process. This never happens in ordinary chemical reactions. In chemical reactions, it is the electrons that are involved , not the nucleus of the atom.
What happens to hydrogen atoms at a very high temptatute?
nuclear fusion is a type nuclear reaction in which 2 or more atoms combine to form heavier atom .
Is the total mass after fusion greater or less than before fusion?
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
What are different types nuclear heat?
fission: nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller partsfusion: nuclear fusion is the process by which two or more atomic nuclei join together "fuse"
Does nuclear fusion involve splitting an atom?
yep
How nuclear fusion and nuclear fission differ in terms of environmental hazards?
Nuclear fission involves splitting an atom and creates radioactive waste. Nuclear fusion involves bringing an atom together and creates no radiative waste
Reaction that involves a change in the nucleus?
The general term is "nuclear reaction". An atom may emit alpha, beta, or gamma rays; it may split into two or three smaller parts (fission), or two lighter atoms may combine into a heavier one (fusion).
Can fusion take place in the nucleus of a uranium atom?
Not fusion, but a fission reaction.
