WebGiant covalent structures. These can only conduct if there are delocalised electron shells over the whole giant structure. Effectively, among the common substances … • Hardness: Very hard, due to the strong covalent bonds throughout the lattice (deformation can be easier, however, in directions that do not require the breaking of any covalent bonds, as with flexing or sliding of sheets in graphite or mica). • Melting point: High, since melting means breaking covalent bonds (rather than merely overcoming weaker intermolecular forces). WebProperties and reactions. In its most stable elemental state, arsenic is a steel-gray, brittle solid with low thermal and electrical conductivity. Although some forms of elemental arsenic are metal-like, the element is best classified as a nonmetal.Other forms have been reported but are not well characterized, including especially a yellow, metastable form, … lithuanian fashion designers
