Question 24

A uranium-235 nucleus absorbs a neutron and splits. The equation for the fission is shown.

{}^{235}_{92}\text{U} + {}^{1}_{0}\text{n} \rightarrow {}^{144}_{56}\text{Ba} + {}^{A}_{Z}\text{X} + 2\,{}^{1}_{0}\text{n}

What are the values of $A\,$ and $Z$ ?

[1]

$A = 90$ and $Z = 36$

$A = 91$ and $Z = 36$

$A = 89$ and $Z = 36$

$A = 90$ and $Z = 38$
