Question 119

92235U^{235}_{92}\text{U}92235​U is an isotope of uranium.

The nucleus can absorb a neutron and then split to form two other nuclei.

Two nuclei that form are barium, 56141Ba^{141}_{56}\text{Ba}56141​Ba, and krypton, 3692Kr^{92}_{36}\text{Kr}3692​Kr.

In this reaction, neutrons are also produced.

What is the number of neutrons produced when the nucleus splits?
