Chapter 2, Problem 44

The elements of Group 14 show an interesting change in properties moving down the group. Give the name and chemical symbol of each element in the group and label it as a nonmetal, metalloid, or metal.

Verified step by step guidance
1
Step 1: Identify the elements in Group 14 of the periodic table. These elements are carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb).
Step 2: Classify carbon (C). Carbon is a nonmetal, known for its ability to form a wide variety of compounds, including organic molecules.
Step 3: Classify silicon (Si) and germanium (Ge). Both silicon and germanium are metalloids, which means they have properties intermediate between metals and nonmetals.
Step 4: Classify tin (Sn). Tin is a metal, known for its malleability and use in alloys such as bronze.
Step 5: Classify lead (Pb). Lead is also a metal, recognized for its density and use in applications like batteries and radiation shielding.
