Question

A californium atom undergoes nuclear fission. Complete the equation by filling in the missing parts.

Answer 1

                            114

The answer is               Pd

                            46

Answer 2

Answer : The missing part is, $^{114}_{46}Pd$

Explanation :

Nuclear fission : It is a process in which a heavy nuclei absorbs a neutron, they split or fission into two small nuclei and 3 neutrons.

Atomic number of Cf = 98

Atomic mass of Cf = 252

Atomic number of Te = 52

Atomic mass of Cf = 136

Atomic number of unknown element = [(252 + 1) - (136 + 3)] = 114

Atomic mass of unknown element = 98 - 52 = 46

So, the unknown element is, palladium (Pd)

The complete nuclear fission of a californium atom will be,

$^{252}_{98}Cf+^1_0n\rightarrow ^{114}_{46}Pd+^{136}_{52}Te+3^1_0n$

Hence, the missing part is, $^{114}_{46}Pd$
