Question 512: Atoms & Nuclei

Question

When a uranium isotope $$_{92}^{235}U$$
 is bombarded with a neutron, it generates $$_{36}^{89}Kr$$ three neutrons and :

Accepted Answer

$${}_{92}^{235}U$$ + $${}_{0}^{1}n$$ = $${}_{36}^{89}U$$ + $${}_{0}^{1}n$$ + $${}_{Z}^{A}X$$
Balancing atomic number on both side, we get
92 + 0 = 36 + Z
So, Z = 56
Balancing mass number on both side, we get
235 + 1 = 89 + 3 + A
So, A = 144
It gives $$_{56}^{144}Ba$$

Answer

$${}_{40}^{91}Zr$$

Answer

$${}_{36}^{101}Kr$$

Answer

$${}_{36}^{103}Kr$$

Answer

$${}_{56}^{144}Ba$$
