What is Radioactive Decay?
Nuclei are made up of protons and neutrons, which are held together by the so-called strong force. Some nuclei have a combination of protons and neutrons that do not lead to a stable configuration. These nuclei are unstable or radioactive. Unstable nuclei tend…

What is difference between excitation and ionization potentials?
Excitation potential The potential required to lift an electron from the ground state to some higher state is called excitation potential. Or If the energy supplied to an electron is such that the electron is lifted from its ground state…

Radioactive carbon dating formula and method
Radioactive dating Any of several methods for determining the age of archaeological and fossil remains rocks, etc, by measuring some property of the organic or inorganic matter that changes with time. This property may be dependent on some aspect of…

Types of Natural Radioactivity
What is Natural-radioactivity? All the elements beyond hydrogen and helium were made in nuclear reactions in the interiors of stars or in explosive supernovas. Both radioactive and stable nuclides are created in these processes. The solar system is composed of…

What are some examples of nuclear reactions?
Nuclear Reaction definition While studying radioactivity, we have seen that an α-particle is emitted from radium-226, and radon-222 is obtained. This nuclear is change is represented by the following equation: Such an equation represents a nuclear reaction. The above-mentioned nuclear…

Nuclear reactor components and types
What is nuclear reactor?How does it works ? In a nuclear power station, the reactor plays the same part as does furnace in a thermal power station. In a furnace, coal or oil is burnt to produce heat, while in…

Types of radioactivity or Radiation
Types of radioactivity are provided here. There are three types of radiation, alpha radiation, Beta radiation, and Gamma radiation. Keep reading.. what is radioactivity? It has been observed that those elements whose charge number Z is greater than 82 are…

Types of radioisotopes and their examples
Radioisotopes are formed by Isotopes, which are atoms with the same atomic number and different mass numbers. Some Types of radioisotopes are Radioactive sodium carbon, phosphorous, Iodine, Gold. Radioisotopes examples Examples of natural radioisotopes are 238 U (uranium), 40 K (potassium), 232 Th (thorium) and their child nuclei (obtained by…
