quantum theory of atomic 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 hybridize..

All these hydrides are covalent in nature and have pyramidal structure. These involve sp 3 hybridization of the central atom and one of the tetrahedral position is occupied by a lone pair. Shape of NH 3 molecule Due to the presence of lone pair, the bond angle in NH 3 is..

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 - N single bond in am..

Atomic Structure and Charges - 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 tight..

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..

Let us right away meet those who scripted a mighty story of a miniscule atom..

Question 1 - Question: What is an electron? State its relative mass and charge. Answer: The electron is a negatively charged particle found in the atoms of all the elements. Its relative mass is 1/1840 a.m.u and relative charge is ..

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..

Bohr's Atomic Model - 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 whic..
