An alpha particle is the. Alpha decay two protons and two neutrons changes the mass number of the element by 4 and the atomic number by 2. These changes are described using nuclear equations.
Fusion is the main nuclear process that occurs in the sun and other stars. Fusion is a process in which two nuclei combine to form a nucleus of larger mass number. Alpha decay two protons and two neutrons changes the mass number of the.
These changes are described using nuclear equations. A nucleus changes into a new element by emitting nuclear radiations. It involves taking smaller nuclei and bringing them together to form a bigger nucleus.
Fusion is the opposite of that. Fission is the process in which large nuclei are split into two smaller nuclei releasing energy in the process. Explain the difference between nuclear fusion and nuclear fission.
Written by the expert teachers at save my exams for the aqa 9 1 gcse physics exam. Free physics revision notes on. This process is the reverse of nuclear fission but it needs more heat to start the reaction and therefore is much more dangerous it takes more energy to start the reaction as the nuclei both have posiitive charges which require huge amount.
It is usually two lighter nuclei making one heavier nuclei meaning that energy is given out. Nuclear fusion is where two nuclei join together into one. Learn about and revise nuclear fission nuclear fusion and how energy is released from these processes with gcse bitesize physics.
The nuclei fuse together and energy is released.
Nuclear fusion equation gcse. Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. In a nuclear reactor a neutron is absorbed into a nucleus typically uranium 235. This causes the nucleus to. Learn about and revise nuclear fission nuclear fusion and how energy is released from these processes with gcse bitesize physics.
Nuclear fusion occurs when two small light nuclei join together to make one heavier nucleus.
