If another proton gets added to the molecule there will be an increase in the atomic number and atomic mass by 1 unit and a new species will form.

here boron is taken which has an atomic number of 5 and atomic mass of 11 so when we add  a proton to it, it will change into carbon having atomic number as 6 and atomic mass as 12.

The new species formed will be .
