When we hear the term ‘fission’, it is easily can be relate to nuclear fission. Nuclear fission take place when a ‘insane’ neutron, usually, clashed with a unstable atom or isotope, it make the unstable isotope to fission, break into small particle. These particle then clash with other unstable isotope, this process known as chain reaction. Chain reaction define as when field of ignite object is ready, all it need is a trigger to get it to go off.

Nuclear Reaction!!!!!

What is fussion and fission?Fission and fusion are two type of energy releasing reactions.This is where energy is being release by atomic bonds within the nucleus. Fusion can be define as combine, where two atoms combine to create a larger atom.Fission can be understood by splits or divide into individuals, where atom divide into two. Therefore, these two are opposing force, they are different. Fusion and fission are also nuclear reaction, which are use to create nuclear weapons.

Fusion can be related to nuclear fusion.where two small low-mass isotopes ‘unified’ to create a big atom, and the energy it release is ENORMOUS. Those isotopes that fuse usually low in mass, hydrogen, and ONLY united under extreme pressure and temperature surrounding.Fusion is better and safer with less radioactive, and it is unlimited supply. Researchers trying to discover ways to use fusion to make positive impact on life.


Unstable isotope: a atoms that have unbalance between proton and neutron in the nucleus, but it seeking to become stable. for this reason, the atom have to release or gain an neutron.

Radioactive Isotopes

Instable of radioactive isotopes ‘aka’ nuclear unstable. What make a radioactive isotopes you ask ? A radioactive isotope can be relate to nucleus being unstable. In a nucleus, the neutron and proton have a ratio where they can manage to make the atom of the nucleus to be in the 'stable zone'. If the ratio change, then the nucleus, or the atom, will go though a phrase of decay until it reach this ‘stable zone’. During this process, if the neutron change, a new isotopes form, if the protons change, a new atom form. This process can also be know as radioactive decay, while the nucleus ‘decaying’ to be in a stable form, it give out radiation in forms of atomic particles or high energy rays.


Chain Reaction

SP2: Student will evaluate the significance of energy in understanding the structure of matter and the universe. a. relate the energy produced through fission and fusion by stars as a driving force in the universe.b. explain how the instability of radioactive isotopes result in spontaneous nuclear reaction.
