structure of atom

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutron..

Introduction - The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atoms. Fa..

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of the experimental facts reg..

Sulphuric acid is a covalent molecule having hexavalent S atom. It has a tetrahedral structure...

Structure - Organic cyanides has a triple bond between the C and N atoms i.e., one sigma and two pi bonds are present. Thus nitrogen here is sp hybridized. The C-C N bond angle is 180 o . Bond length of then the triple bond C N is shorter than the double bond C=N in imines and C..

Hydrogen is the simplest element with its atom having only one electron. Hence, the atomic spectrum of hydrogen has played a significant role in the development of atomic structure. In the emission spectrum of hydrogen, when an electric discharge is passed t..

6 0 molecule C 6 0 molecule has marvelously symmetrical structure. It is a fused-ring of aromatic system containing 20 hexagons and 12 pentagons of sp 2 hybridized C atoms. The structure bends around and closes to form a soccer ball shaped molecule. C 6 0..
