In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. ...
This invention relates to a novel photosensitive element comprising: a support having a surface; a photosensitive layer on the surface; and a transparent, protective coating on the photosensitive layer. The photosensitive layer comprises a composition of an ethylenically unsaturated compound and a photo...
This is a method of metal or metal compound extraction from an ore through pre-treatments that involve the use of a leaching agent, separation of impurities and precipitation. It is used in the extraction ofuranium, gold, zinc, silver and copperfrom low-grade ores. ...
What characteristic distinguishes element from compound? a) Define the nephelauxetic effect. b) Briefly discuss the trends in the nephelauxetic series of ligands in terms of the covalent character of complexes and the softness of ligands. Use atomic or molec...
