35.THE ATOMIC STRUCTURE -OTHER SUB ATOMIC PARTICLES.

In this post we shall just get an overview of some recently discovered sub atomic particles.It was believed  that the entire universe was made up of atoms and that atoms are in turn made up of electrons, protons and neutrons.With the wave-particle duality and concepts of quantization, it was assumed that we had cracked the…

34.THE ATOMIC STRUCTURE- Heisenberg’s Uncertainty Principle.

Werner Heisenberg, was a German theoretical physicist,who  was studying under Sommerfield.Sommerfield knew about Heisenberg’s interest in Niels Bohr’s thesis and so he introduced him to Bohr’s idea of Quantum Mechanics.Later,Heisenberg started working with Niels Bohr in 1924.He  completely supported Bohr’s idea of the atom. Heisenberg was a very young ,competitive man.He was exceptionally talented.At the…

33.THE ATOMIC STRUCTURE – Schrödinger Equation.

The contention between Albert Einstein and Neils Bohr was carried forward and taken to a new level by their respective students – Erwin Schrödinger and Werner Heseinberg respectively ,who were hell-bent to prove that their respective theories about the atom were correct. Let us begin talking about these very talented men ,who went head-to-head to prove that…

31.THE ATOMIC STRUCTURE -Experimental validation of de Broglie’s thesis.

Any scientific thesis,even if it is scrupulously proved to be true in theory, is not considered absolute , until it is proved by experimental data.As a theoretical physicist, Louis Victor de Broglie , was successful in proposing an idea , which seemed very plausible as it corroborated Niel’ Bohr’s quantum condition.However, without a valid proof,…

30.THE ATOMIC STRUCTURE – Wave-Particle Duality,De broglie’s thesis.

In this post we will start our discussion with a series of new developments in the field of atomic chemistry, which changed the way we look at matter.As scientists dug deeper,they were forced to abandon everything they believed in earlier and discover a whole new science- a science which seemed implausible even to the geniuses who…

29.THE ATOMIC STRUCTURE – Discovery of neutron.

In the 19th century,the research on the structure of the atom was yielding such incomprehensible results that scientists worldwide were astounded by its revelations.However, this also stoked up the desire to find out more about the atom and thus the nature of the universe. It is remarkable though that admist this research , a very…

28.THE ATOMIC STRUCTURE -Pauli’s exclusion principle,Afbau Principle,Hund’s rule of maximum multiplicity,Electronic Configurations.

The Nobel Prize for Chemistry this year is awarded to three great chemists namely,Jean-Pierre Sauvage(University of Strasbourg,France) ,Sir J. Fraser Stoddart(Northwestern University , USA) and Bernard L. Feringa (University of Groningen, the Netherlands)“for the design and synthesis of molecular machines” .They have developed world’s smallest machines – molecules with controllable movements.These can perform tasks when energy is…

27.THE ATOMIC STRUCTURE – Quantum Numbers.

In the last post we saw how quantum numbers were introduced to understand the structure of the atom.These quantum numbers described all the necessary parameters about an electron in a given orbit.Let us begin by understanding what these quantum numbers exactly tell us. A] The Principal Quantum number (n)– This parameter divulges information about the…
