Concept explainers
(a)
Interpretation:
Whether the property of shiny solid is possessed by a metal or nonmetal is to be stated.
Concept introduction:
An element is the basic unit of a substance that cannot be broken down into any smaller units. An element can be classified as metal, nonmetal or metalloid. A metalloid has the properties in between the metals and nonmetals. A metal possess certain characteristic properties like malleability, ductility, shiny appearance and so on. On the other hand, a nonmetal can be characterized by its peculiar properties like brittleness, low density, low melting point etc.
(b)
Interpretation:
Whether the property of brittle solid is possessed by a metal or nonmetal is to be stated.
