Sub Atomic particles

  1. 1. Topic: Sub Atomic Particles: Overview, Types & Significance Submitted By: Name: D.Sairam ( 1st Sem IBT) Teacher: Dr. Vineet Sharma Course Code: BSBT-102 ( Chemistry for Biologists) Assignment Code: U2P1 Source: www.britannia.com/images
  2. 2. Overview • Introduction • Types of Sub-Atomic Particles • Quarks • Leptons • Bosons • Significance
  3. 3. Introduction • Subatomic particles are particles that are smaller than atoms. They are present within an atom and cannot be seen by our naked eyes. • They have their own distinct characters and are mainly of two types of Elementary Particles and Composite Particles. • Protons and neutrons are Composite Particles while Electron is an Elementary Particle.

  6. 6. Quarks can be observed in Hadrons such as Baryons i.e. in particles such as Protons and Neutrons. Murray Gell-Mann (Right) and George Zweig Source: a) Google Images b) www.sciencedaily.com/Quarks

  8. 8. This is Positronium ,a system that combines Electron with it’s anti particle Positron. It ( system) is highly unstable as the duo react to give two 2 Gamma particles. It's lifespan is around 125 picoseconds. Source: www.wikipedia.org/positro nium
  9. 9.  Either Elementary or Composite Types of Elementary Bosons a) Scalar or Zero Spin – Higgs Boson b) Gauge or Force- Gluon, Photon and W and Z Boson.  Composite: Meson  Graviton ( Hypothetical so far) Bosons Source: www.google.com/images

  11. 11. Significance of Sub Atomic Particles • They are produced in cosmic rays and during scattering processes in particle accelerators. • Electron, arguably the most important Sub-Atomic Particle helps in studying and identifying Chemical Properties of Elements. • Proton Therapy is a type of treatment that can be used to treat Cancers. • Elimination or Turning off the Higgs Field can result in rapid Communications and Transmission of Signals. • Positron is used in PET scan that treat many ailments and maladies. • Most of the Gauge Bosons are used in Super fluidity.
