Answers
An element E exists in three allotropic forms A,B and C. In allotrope A, the atoms of element E are joined to form spherical molecules. In allotrope B, each atom of element E is surrounded by three E atoms to form a sheet-like structure. In allotrope C, each atom of element E is surrounded by four other E atoms to form a rigid structure.
(a) Name the element E.
(b) What is allotrope A?
(c) What is allotrope B?
(d) What is allotrope C?
(e) Which allotrope is used in making jewellery?
(f) Which allotrope is used in making anode of a dry cell?
ANSWER
(a) Element E is Carbon since Carbon has the three mentioned allotropic forms.
(b) Allotrope A is Buckminsterfullerene.
(c) Allotrope B is Graphite.
(d) Allotrope C is Diamond.
(e) Allotrope C that is Diamond is used in making jewellery.
(f) Allotrope B that is Graphite is used in making anode of a dry cell.
