quantum theory of atomic structure

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..

The compounds can be branched when the carbon atoms are more than three . Some of the examples are: Name Formula Number of carbon atoms..

Example: 1 24 Mg..

A story unfolds - Structure of atom - Let us right away meet those who scripted a mighty story of a miniscule 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 neutrons. As the protons are ..

Summary - Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to the discovery of electron. Goldstein's experiment with the discharge tube having a perforated cathode led to the discovery of ..

Determination of the Structure of a Complex Using Werner's Theory - Example: In the complex between CoCl 3 and NH 3 the ionizable chloride ions are found by precipitation with AgNO 3 . The remaining Cl and NH 3 are present around the central Co in such directions so as to minimi..

In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: An atom consists of a small, heavily positively charged nucleus around which electrons revolve in defini..
