(a)
Interpretation:
Aluminum has to be identified as metal, nonmetal or metalloid.
Concept Introduction:
Metals: Metals have the ability to conduct heat and electricity. They are solids are room temperature and present on the left of the periodic table. They have low ionization energy and low
Nonmetals: Nonmetals are poor conductors of heat and electricity. They are present on right of the periodic table. They have high ionization energy and high electron affinities. They gain electrons to form anions.
Metalloids: Metalloids are elements that have intermediate properties between metal and nonmetals. These are solids at room temperatures and forms alloys with other metals.
