Q.4
What is nuclear fission?
0%
It is the process by which stars generate light and heat
0%
Fission is the splitting of an atomic nucleus creating two smaller atomic nuclei
0%
Fission is the fusion of two atoms to create a heavier atom
0%
Fission is the process by which electrons are removed from an element
Q.5
What happens to the excess neutrons?
0%
They decay into protons and electrons
0%
They decay into electrons
0%
They are absorbed by other atoms creating more atoms to split into smaller atoms
0%
They bond with other free neutrons to create a large neutron mass
Q.6
In nuclear power stations, a chain reaction is required. What is a chain reaction?
0%
Reactions in which one reaction causes further reactions, which cause further reactions etc.
0%
Reactions in which when the first reaction has occurred others are prevented
0%
Reactions in which when a certain number of reactions have occurred others are prevented
0%
Reactions which will never stop
Q.7
What happens to the atom after it absorbs a neutron?
0%
The atom becomes unstable and decays into two smaller atoms releasing more neutrons and energy
0%
It loses an electron
0%
It loses a proton
0%
The neutron is ejected
Q.8
What is an advantage of nuclear fission?
0%
