Since the av.no. Therefore it could be predicted to have a metallic bond. Question 23 . The ease of separating atoms or molecules with heat is similar to the ease of separating atoms with force. In the fig., the slope of material A at zero force is greater than that of B. Hence A has a higher melting temperature than does B. Question 26.
Elastic modulus is one of the properties that can be determined from the bond energy curve.
This is the case with many oxide ceramics and other ionic solids. It rather asks the reason for the similarity of the value in many of the oxide ceramics eg. Question 31 . In the Ketone the C is located within an equilateral triangle. Here the N is at the center.
