Question

Non-metals do not show ductility due to absence of:

• A. metallic bonds which allow one electron to slip over another
• B. covalent bonds which gives strength
• C. ionic bonds which gives makes it hard
• D. co-ordinate bonds which which gives extra stability

Answer 1

Answer: (A)

metallic bonds which allow one electron to slip over another

Non-metals do not show ductility due to absence of metallic bonds which allow one electron to slip over another. High degrees of ductility in metals occur due to metallic bonds. In metallic bonds valence shell electrons are delocalized and shared between many atoms. The delocalized electrons allow metal atoms to slide over one another without being subjected to strong repulsive forces that would cause non-metals to shatter.
