factors influencing electron availability

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electrons..

The inter-ionic attraction - It is the intersection between the ions of the solute at low concentrations. It is not much at low concentrations the inter-ionic cone is very less, but at high concentrations it is appreciable. fig 5.1 The negative ion is pulled to the negative pole because it is surro..

During the formation of monosubstituted products in benzene as all the six hydrogens are equivalent any of the six positions can be occupied. But, when the monosubstituted product is to be converted into disubstituted one, the existing substituent present in the ring directs the incoming group to ..

Electron Displacement in Covalent Bonds - Organic compounds mainly consist of covalent bonds. The displacements of the electron pairs in these covalent bonds may take place either on their own or under the influence of other species. Three types of electron d..

Organic compounds mainly consist of covalent bonds. The displacements of the electron pairs in these covalent bonds may take place either on their own or under the influence of other species. Three types of electron displacements are generally noticed in the mech..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most limiting factor..

The charge to mass ratio is found by measuring the deflection of a ray under the simultaneous influence of electrical and magnetic fields, applied perpendicularly to each other as well as to the direction of the flow of light. This is illustrated in the figure below:..

Climatic Factors - Atmospheric Gases - The gases present in the atmosphere are chiefly oxygen, carbon dioxide and nitrogen which greatly influence the living organis..

Interactions among the organisms in a community, as called biotic factors, influence the structure, composition and function of a community. In succession, during period of time a community makes the area less favourable for itself and more favourable for the next serial commun..

Temperature is one of the essential and changeable environmental factors. It penetrates into every region of the biosphere and profoundly influences all forms of life by increasing or decreasing some of the vital activities of the organism. It is frequently a limiting ..
