Because the positive charge of each atom’s nucleus is balanced by the negative charge of its outer electrons, a molecule is neutral. The movement of electrons from one region of … Read more
Adsorption is a surface phenomenon that involves the accumulation of molecular species on the surface rather than within the bulk of a solid or liquid. A substance that accumulates on … Read more
The Grignard reagent is an organomagnesium compound with the chemical formula R – MgX, where R represents an alkyl or aryl group and X represents a halogen. In general, they are … Read more
Halogenation of alkane involves the replacement of one or more hydrogen atoms in organic compounds by halogen atoms (like F, Cl, Br, I). It is the simple substitution reaction in … Read more
The p-block elements with higher atomic numbers [e.g., Ga, In, Tl (Gr IIIA), Ge, Sn, Pb (Gr IVA), and As, Sb, Bi (Gr VA)], display two oxidation states they are: … Read more
The atomic radius of an element is the typical distance from the center of the nucleus to the boundary surrounding the electron cloud. Since the boundary is not a well-defined … Read more
Electron affinity is the energy released when an electron is added to a neutral, gaseous, and isolated atom in its ground state to form a monovalent anion. It is a … Read more
These are the compounds in which the central atom lacks eight electrons in its valence shell or possesses eight electrons but can expand the valency due to the presence of … Read more
Aluminium is a noncorrosive lightweight silvery-white metal. It is included in the boron group (Group III a) in the periodic table. Aluminium is the most abundant metallic element on earth … Read more
