Explanation / Answer

Nuclear reacton you have to see atomic numer and mass number count before and after reaction it must be same. in above reaction first we mach the mass number 249+A=260+(4*1)

therefore unknown element mass number A=15

similarly equating the atomic number 98+Z=105+(4*0)

atomic nuber Z=7, means that is nitrogen atom

the unknown element is 7N15

so over all reaction 98Cf249+7N15=105Db260+40n1
