Isotopes are the same elements with the same number of portions but different numbers of neutrons
For instance, the element carbon exists as several isotopes, each having the exact same number of protons (otherwise, it would no longer be carbon if the # of protons changes), and a different number of neutrons
There is a shortcut trick while doing such fill in the blanks of nuclear reactions of hydrogen and helium
Let a,b,care elements of set N
Now
for our question
Hence b=4-3+1=1+1=2
So
The missing place should b e deuterium of heavy water
In nuclear reactions energy is released so it's mentioned on product side not reactant side
