| We have seen that an atom is made up of atoms and electrons which are measured. Ordinary chemical reactions (such as the combustion and salting reactions) are just a matter of changes in the shell, especially the electrons in the outer shell, while the atomic nucleus does not change. |
Nuclear reaction
Reactions that include changes in the nucleus are called nuclear reactions or reactions (nucleus).
There are nuclear reactions that occur spontaneously or artificially. It's a good thing to do.
Spontaneous nuclear reactions occur in unstable nuclei. Substances that contain this unstable nucleus are called radioactive substances.
Meanwhile, non-spontaneous nuclear reactions can occur in a stable nucleus or an unstable nucleus. Nuclear reactions are accompanied by changes in energy in the form of radiation and heat.
Various types of nuclear reactions are accompanied by very intense heat liberation, greater than normal chemical reactions. Today, nuclear reactions have been widely used for peaceful purposes (not military purposes) both as a source of radiation and as a source of energy and its use in the health sector.
