Melting point of covalent solids
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, … WebSubstance A is malleable, ductile, conducts electricity well, and has a melting point of 1135 °C. Substance B is brittle, does not conduct electricity as a solid but does when molten, and has a melting point of 2072 °C. Substance C is very hard, does not conduct electricity, and has a melting point of 3440 °C.

WebCovalent bonds are directional where the atoms that are bonded showcase specific orientations relative to one another. Most compounds having covalent bonds exhibit relatively low melting points and boiling points. Compounds with covalent bonds usually have lower enthalpies of vaporization and fusion. WebFor example, some covalent compounds, such as carbon, can have very high melting points if they have strong covalent bonds. Additionally, some ionic compounds, such as those with large or highly charged ions, can have relatively low melting points. One specific example is sodium chloride (NaCl), an ionic compound, which has a melting point of ...
