Hence boron trihalides act as Lewis acids. They rapidly combine with electron donors such as NH 3 , F - ion, amines, ether, sulphides or phosphorus. The other halides of Group 13 elements have halogen bridged dimeric structures as shown below for aluminium (III) chloride, which exists as ..

Molecular orbital energy level diagram gives very valuable information regarding the behaviour of molecules. The important information conveyed by the electronic configuration of a molecule ..

Upto the year 1924, electron was exclusively regarded as a particle. However, in 1924, de-Broglie suggested that an electron behaves both as a material particle and as a wave. Just like light, some experimental facts can be explained by assuming electrons as tiny part..

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 orbital, while a single electro..

Cyclic Electron Transport System - Cylic reaction transport occurs only occasionally when synthesis of carbohydrate is curtailed due to limited supply of CO 2 and NADPH 2 starts accumulating. At this time, there would be no need for additional NADPH 2 . Moreover, the cyclic electronh..

This theory was proposed by H. Lundegardh, who suggested that anions could be transported across the membrane by cytochrome system. Energy is supplied by direct oxidation of respiratory intermediates. Diagrammatic representation of cytochrome pump hypothesis On salt absorption, anions (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 ..

Shapes of Atomic Orbitals - 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..

Magnesium, whose atomic number is 12, has 2, 8, 2 configuration. Its valence shell has two electrons. The electronic configuration of chlorine (At. no. 17) is 2, 8, 7. It has seven valence electrons. Since, magnesium has two electrons in excess of the neon c..

The electronic configurations of aluminium (At. no. 13) and fluorine (At. no. 9) atoms are 2,8,3 and 2,7 respectively. Aluminium has 3 electrons in excess of its nearest noble gas (neon) configuration. Fluorine is one electron short of its nearest noble gas (neon) con..
