Explanation / Answer

Let the reactant be X

Balance mass number on both sides

mass of Cf + mass of X = mass of Sg + mass of n

1*249 + M = 1*263 + 4*1

M = 18

Balance atomic number on both sides

atomic of Cf + atomic of X = atomic of Sg + atomic of n

1*98 + A = 1*106 + 4*0

A = 8

Atomic number 8 is for element O

So, the reactant is

18-O

Answer: 188O
