Explain whether silicon or diamond has a higher melting point in terms of bonding and structure
Both silicon and diamond has a giant covalent structure. Both silicon atoms in silicon and carbon atoms in diamond are held by strong covalent bonds. 156Please respect copyright.PENANA5ATj1wwlMg
However, a carbon atom has a smaller atomic size than a silicon atom.156Please respect copyright.PENANA77L7XgU5l3
Thus the C-C bond in diamond is shorter than the Si-Si bond in silicon. 156Please respect copyright.PENANAmx35gVPp2g
Hence, the covalent bond between carbon atoms in carbon are stronger than those between silicon atoms in silicon.
A larger amount of energy is needed to break the covalent bond between carbon atoms in diamond. 156Please respect copyright.PENANAFeTqXJxllV
Diamond has a higher melting point.
