atomic structure filling of electrons in orbitals

(a) Formation of a planar hexagonal structure due to overlapping of the sp 2 hybrid orbital of each carbon atom with its neighboring carbon atoms and hydrogen atoms. (b) A unhybridized 2p orbital on each carbon lies perpendicular to the ca..

The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with Aufbau principle as already d..

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 square will mean an empty o..

>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 a..

An atomic orbital is the space around the nucleus in which the probability of finding the electron is maximum. These most probable regions can be diagrammatically represented by cloud density (dot) diagrams. The density of dots (or lack of them) in any region of the cl..

Atomic Orbitals - Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the..

Each molecular orbital can accommodate maximum of two electrons having opposite spins. This is in accordance with Pauli's exclusion principl..

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 ..

Valence Shell and Valence Electron - The outermost shell of an atom is called its Valence shell. It is the decisive shell during a chemical reaction. The electrons of only this outermost shell are involved during chemical combinations; electrons are either gi..
