Graphite number of covalent bonds
WebDue to the strength of the covalent bonds, covalent network solids have high melting points. Three-dimensional network solids (such as diamond or silica) are hard and rigid, whereas two-dimensional network solids (such as graphite) are soft due to the ease with which the network layers can slide past each other. Created by Sal Khan. Sort by: WebSimple molecular structures will have a set number of covalent bonds. For example, all water molecules have two covalent bonds, one bonding each of the two hydrogen atoms to the central oxygen atom. We call these units molecules. The chemical formula is simply the makeup of each molecule.

WebCarbon forms unusually strong C-C single bonds, C=C double bonds, and carbon-carbon triple bonds. 2. The electronegativity of carbon ( EN = 2.55) is too small to allow carbon to form C 4- ions with most metals and too large for carbon to form C 4+ ions when it reacts with nonmetals. Carbon therefore forms covalent bonds with many other elements. 3. cinnaminson tree lightingWebAnswer : graphite is a Covalent bond. What is chemical bond, ionic bond, covalent bond? Chemical bond.
