Electronic Configurations and Molecular Behavior
Stability of a Molecule We have learnt that the electrons in bonding molecular orbitals contribute to attraction between the atoms and thereby help in the formation of bond. On the other hand the electrons in antibonding molecular orbitals..
Structure of the Atom
>The mass of electrons is negligible compared to the mass of the protons. Ordinary hydrogen is the only element that has no neutron in it. According to Bohr electrons revolve around the nucleus in fixed orbits called K, L, M, N etc. The energy of the shells increases as the distance form ..
Molecular Level
Atoms of chemical elements combine with one another to form molecules. A molecule may have atoms of the same element (like O 2 , H 2 , N 2 ) or of different elements (like H 2 O, CO 2 , CH 4 etc..
Multi-electron atoms
In these atoms the energy of orbitals have the same values of 'n' but different values of 'l'. Thus both values of 'n' and 'l' determine the energy of an orbital. The following hold good for multi-electron atoms. Different orbitals..

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 positively..
Electronic Configurations of Atoms
Electronic Configurations of Atoms - The distribution of electrons in different orbitals is known as electronic configuration of the atom. The orbitals are indicated by a box (square or circular) and electrons are indicated by arrows. An empty squar..
Bohr's Model of an Atom
Bohr's Model of an Atom - Rutherford's model had a major drawback. It could not explain why ultimately electrons did not fall into the nucleus by taking a spiral path. This was in concurrence with the electromagnetic theory that states 'if a charged particle undergoes accelerated motion t..

. But when an electron jumps from a lower energy level to a higher one, some energy is absorbed while some energy is emitted. When an electron jumps from a higher energy level to a lower one, the amount of energy absorbed or emitted is given by the difference of energies associated with t..
Atoms and Nuclei Summary
Bohr improved upon Rutherford model postulating that electrons can revolve around the nucleus in certain discrete, non-radiating orbits, called stationary orbits, for which total angular momentum of revolving electron is an integral multiple of h / 2 p where h is Planck's consta..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
This was very helpful. I did a lot of the problems myslef and it was building my confidence -owen
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
