1
Q
forms of energy released during nuclear reactions
A

fission
radioactive decay
2
Q
nuclear fission
A
the splitting of a large, unstable nucleus into 2 smaller nuclei
3
Q
what is used as fuels in nuclear power stations
A
isotopes of uranium and plutonium
4
Q
spontaneous fission
A
when a nuclei undergo fission without additional energy being put to nucleus
5
Q
what has to happen for fission to occur
A
unstable nucleus must absorb a neutron
6
Q
products of fission
A
- 2 smaller nuclei
- two or three neutrons
7
Q
chain reaction
A
process of neutrons released by fission being absorbed by another unstable nuclei and inducing further fission.
