emits a beta particle forming an element Q. Q can be represented by
The element `""_11^24 "Na"` changes to magnesium by the emission of a beta particle. Write down the symbolic equation for the beta emission.
What do you mean by nuclear energy? What is responsible for its release?
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 radioactive nucleus undergoes a series of decays according to the sequence
\[\ce{X->[β] X1->[α] X2->[α]X3}\]
If the mass number and atomic number of X3 are 172 and 69 respectively, what is the mass number and atomic number of X?

How does the position of an element change in the periodic table when it emits out a beta particle?
Complete the following fission reaction:
\[\ce{_92U^235 _0n^1 -> _aSb^133 + _41Co^b + 4_0n_1 + energy}\]
Write down the values of a and b.
