A nuclear reaction is represented by the equation:
`""_1^2H+_1^2H->_2^3He+xc+E`
What does E represent?
A nuclear reaction is represented by the equation:
`""_1^2H+_1^2H->_2^3He+xc+E`
State two conditions under which such a reaction takes place.
A nuclear reactor has half the length of all its control rods inserted in graphite. What must be done so that the reactor produces more heat? Explain your answer.
Which of the following statements are correct?
Electrons have
In what way are these numbers related to the isotopes of an element?
Name the following nuclear reaction:
\[\ce {^235_92U +^1_0n-> ^90_38Sr + ^143_54Xe + 3^1_0n + γ}\]
Two statements are given - one labelled Assertion (A) and the other labelled Reason (R).
Assertion (A): In the process of nuclear fission, the amount of nuclear energy generated by the fission of an atom of uranium is so tremendous that it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
Reason (R): The nucleus of a heavy atom such as uranium, when bombarded with low energy neutrons, splits apart into lighter nuclei. The mass difference between the original nucleus and the product nuclei gets converted to tremendous energy.
A nucleus `"_11Na^24` emits a beta particle to change into Magnesium (Mg).
(i) Write the symbolic equation for the process.
(ii) What are numbers 24 and 11 called?
(iii) What is the general name `"_12^24Mg` with respect to `"_11^24Na`?
