Which of the following materials is the poorest electrical conductor? (A) Copper (B) Aluminum (C) Graphite (D) Brass To which wire is the metallic case of an electric appliance connected? Give the reason. How do noble gases differ from other elements?
Graphite is an allotrope of carbon. graphite each carbon Atom is linked with 3 other carbon atoms by single covalent bond resulting in the hexagonal ring which is arranged in a layer. In general, graphite is used in pencil laid, batteries as an electrode. It has 2-dimensional layers like s...
Two or more electron rich-donor groups (ligands) in the form of ions or molecules, can form dative bonds with a metal cation center to form a coordination complex. A dative bond is a covalent bond, in which all of the shared valence electrons come from the ligand itself. The total ...
Graphite is insoluble in water. It has a high melting point and isa good conductor of electricity, which makes it a suitable material for the electrodes needed in electrolysis . Each carbon atom is bonded into its layer with three strong covalent bonds. ...
bonding electrons are shared unequally between two atoms but are not completely transferred.Such bonds are said to be polar covalent bonds and the bond polarity is due to difference in electronegativity, the ability of an atom in a molecule to attract the shared electrons in a covalent bond. ...
