Select the group 4A element that best fits each of the following descriptions.
b. Is the least dense semimetal

검증된 단계별 안내

Identify the elements in group 4A (14) of the periodic table: Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).

Determine which of these elements are classified as semimetals (metalloids).

Recognize that Silicon (Si) and Germanium (Ge) are the semimetals in group 4A.

Compare the densities of Silicon and Germanium to determine which is the least dense.

Select the element with the lower density as the least dense semimetal in group 4A.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Group 4A Elements

Group 4A of the periodic table includes elements such as carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). These elements exhibit a range of properties, including varying densities and metallic characteristics. Understanding the position of these elements in the periodic table helps in predicting their behavior and properties.

Semimetals

Semimetals, or metalloids, are elements that have properties intermediate between metals and nonmetals. They typically exhibit some metallic luster and electrical conductivity but are brittle and not malleable. In Group 4A, germanium (Ge) and silicon (Si) are commonly recognized as semimetals, making them important in electronics and materials science.

Density of Elements

Density is a physical property defined as mass per unit volume, and it varies significantly among elements. In the context of Group 4A, the density of semimetals can be compared to identify which is the least dense. For example, silicon has a lower density than germanium, making it the least dense semimetal in this group.
