What difference between Nuclear Reaction and Chemical reaction?
Difference between nuclear fission and nuclear fusion
Ans:- According to group displacement law: When a radioactive element emits α-particles from its nucleus, the atomic number of the new element or daughter element created is reduced by two units, and four units reduce the atomic weight.
Who gave the group displacement theory?
Ans:- The fresh and starting element will have the similar atomic number. So by Group displacement law position of the fresh and daughter element in the periodic table will remain as it was earlier. The law which is explained above “Group Displacement Law” was specified in 1913 by Fajan and Soddy.
Artificial transmutation : it is a conversion of an elements into another element by bombarding it with a fundamental particles. For example - nitrogen can be transformed into oxygen by bombarding on Alpha particles into the nucleus of nitrogen.
Radioactivity of an elements: when it undergoes a chemical change to a form a chemical compound neither increase or decrease. It is on nuclear phenomenon and does not involved extra nuclear
How Alpha particles/ray are produced?Ans:- When the nucleus of an atom becomes on stable and Alpha particle are emitted to be restore balanced. Particles decay occur in element with high atomic number ie. Uranium, Radium and thorium.
Beta particles/ray are produced? Ans:- It is emitted from the nucleus of an atom during radioactive decay.
Write any five uses of radioisotopes. Ans:-
- Used in medical sector.
- Used in the study of art and humanities with research and applied.
- Used at electric generating
- Used in food preservation and sterilization
- Use at develop disease resistance variety of agricultural plant.
The forms of radioactive in the use such as CT scan carbon dating, production disease resistance of plants variety , thermal Power electric generating, etc.
Define following topics:-Nuclear Reaction : nuclear reaction is a reaction for new element is formed from the parent elements.
Thermonuclear reaction: The large amount of energy is required to initiate these reaction and such energy is received from nuclear fission reaction this reaction can be called thermonuclear reaction.
Atomic bomb: It is a blast based on nuclear fission reaction.
Hydrogen bomb: It is a fusion bomb.
