electric dot diagrams

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 Al 2 Cl 6 ..

It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is meaningless to add vector quantities of ..

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 tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the..

. Just as for a given tube, the current of fluid flowing out depends on its viscosity, the electrical current flowing for a given potential difference depends on the electrical resistance of the conducto..

To detect a charge on a rod 'A' or 'B' bring the rod near to the metallic disc or cap of the electroscope. In either case the leaf diverges as shown in the diagram. ..

Consider the statement of a theorem "If a transversal intersects two parallel lines, then pairs of corresponding angles are equal”. This theorem has two parts. If (hypothesis) and then (conclusion). Let us interchange the hypothesis and conclusion and write the statement. "If a..

Types of Magnets - There are two major types of magnets: Permanent magnets and Temporary magnets. Permanent magnets retain their magnetism over a long period of time whereas temporary magnets retain their magnetic properties only under certain conditions like presence of a strong magnet or an ..
