Here in nuclear reaction we can say that sum of neutrons and protons in reactant side and product side will be same always

Here mass number on the product side is given to us

so sum of mass number is given as


A_1 + A_2 = 265 + 1 = 266

now on the reactant side also the number must be same


A_1' + A_2' = 58 + x

now we will have


58 + x = 266


x = 208

Now number of protons on product side is given as


P_1 + P_2 = 108 + 0

now we also know that atomic number of Fe is 26

so now we will have


P_1' + P_2' = 108


26 + P_2' = 108


P_2' = 82

now the equation is given as


_(26)^(58)Fe + _(82)^(208)Pb = _(108)^(266)Hs + _0^1X
