Identify each of the following elements as a metal, nonmetal, or metalloid: (a) germanium, (b) bismuth, (c) sul- (d) calcium, phur, (e) rhenium, (f) tin.

To determine the classification of the elements, find them on the periodic table. You can use a physical periodic table or an online version.

The periodic table is divided into categories based on the properties of the elements. Metals are generally found on the left-hand side and center of the table, nonmetals are on the right-hand side, and metalloids are found between metals and nonmetals on a diagonal line called the "stair-step." Use the location of each element to determine its classification. (a) Germanium (Ge) - Locate Germanium in group 14 and period 4 on the periodic table. It is near the stair-step, so it is classified as a metalloid. (b) Bismuth (Bi) - Locate Bismuth in group 15 and period 6 on the periodic table. It is located on the left side of the table, so it is classified as a metal. (c) Sulfur (S) - Locate Sulfur in group 16 and period 3 on the periodic table. It is located on the right side of the table, so it is classified as a nonmetal. (d) Calcium (Ca) - Locate Calcium in group 2 and period 4 on the periodic table. It is located on the left side of the table, so it is classified as a metal. (e) Rhenium (Re) - Locate Rhenium in group 7 and period 6 on the periodic table. It is located in the center region of the table, so it is classified as a metal. (f) Tin (Sn) - Locate Tin in group 14 and period 5 on the periodic table. It is located on the left side of the stair-step, so it is classified as a metal.

To conclude, these are the classifications for the elements given: (a) Germanium (Ge) - Metalloid (b) Bismuth (Bi) - Metal (c) Sulfur (S) - Nonmetal (d) Calcium (Ca) - Metal (e) Rhenium (Re) - Metal (f) Tin (Sn) - Metal
