Question d
Identify the bond structures represented below: (i) (ii)
Worked Solution & Example Answer:Identify the bond structures represented below: (i) (ii) - Leaving Cert Engineering - Question d - 2008
Step 1
(i) Identify the bond structure
Answer
The bond structure represented in part (i) is an ionic bond. In ionic bonding, ions are held together by electrostatic forces, typically with larger negative ions and smaller positive ions. This results in a structure that tends to be hard and brittle.
Step 2
(ii) Identify the bond structure
Answer
The bond structure represented in part (ii) is a metallic bond. In metallic bonding, cations are surrounded by a 'sea' of delocalized electrons. This arrangement gives metals their distinctive properties, such as being malleable, ductile, and conductive.
