Isotopes, like everything around us, are varieties of atoms – the smallest particles of matter that retain all the chemical properties of an element. Isotopes are forms of the same chemical element that have certain properties.
The periodic table presents various chemical elements.
Each element differs from another in the number of protons, neutrons and electrons in its composition. Each chemical element's atom contains a certain number of protons and electrons, but the number of neutrons – which is important – can vary.
Atoms with the same number of protons and different numbers of neutrons are called isotopes. They have almost the same chemical properties, but differ in mass, and therefore in physical properties.
There are stable isotopes, which are not radioactive, and unstable isotopes, which, on the contrary, emit radiationThe latter are called radioisotopes.
