Difficulty: easy
Learning Objective 1: Explain the arrangement of the elements on the periodic table and classify elements as metal, nonmetal or metalloid.
Section Reference 1: Section 3.2
Solution: Metals are solids at room temperature except for mercury which is a liquid. The properties of metals include luster, ductility, malleability, and good conductivity of heat and electricity. Metals generally form positive ions. A nonmetal is an element that has properties opposite those of a metal. Nonmetals lack luster, they have relatively low melting points and densities, and are generally poor conductors of heat and electricity. Nonmetals may be solids, liquids, or gases at room temperature and pressure. Nonmetals usually form negative ions.
