Atomic Structure of Selenium
Introduction to Atomic structure of selenium:
The way the electrons of an atom are arranged, it is called electron configuration. It is related to the way electrons are distributed in the orbitals of atom or molecule. With each electron configuration, energy is associated. Upon certain conditions, electrons will be able to move from one orbital to another orbital. In this process, they emit or absorb quantum of energy, in the form of a photon. The periodic table of elements structure can be understood by having knowledge of the electron configuration of different atoms. The chemical bonds that hold atoms together can also be explained using this concept. The peculiar properties of lasers and semiconductors can be explained by the same concept. Around an atom nucleus, there is an orbit followed by electrons is called an electron shell. Each shell has a fixed number of electrons, which it can take. Let us go through the atomic structure of selenium.
Properties of Selenium & its Atomic Structure
Selenium discovered in 1817 by Jons Berzelius. It originates from Greek word “Selene” meaning moon. It is mainly used in photoelectric cells and TV cameras. It is produced by refining metals like lead, nickel or copper.
34 is Selenium’s atomic number. 78.96 amu s its atomic mass. 217 degree Celsius is its melting point. 684.9 degree Celsius is its boiling point. It has 34 protons and 45 neutrons. It is classified as non-metal. Hexagonal is its crystal structure. 4.79 g/cm3 is its density.
The number of energy levels is 4. 2 is the first energy level. 8 is the second energy level. 18 is the third Energy Level. 6 is the fourth energy level.
Isotope Half Life’s are as follows: Se-73 has 7.15 hours. SE-74 is stable. Se-75 has 119.78 days. Se-76, Se-77, Se-78 are stable. Se-79 has 65000 years. Se-80 & Se-82 are stable.
Conclusion for Atomic Structure of Selenium:
As per the discussion on atomic structure of selenium, we came to know that, selenium is widely used in dietary supplements and there are live stock feeds, which are fortified with selenium. Because of its both biological and non-biological application, it is an import chemical to humankind.
