Which characteristic describes lead as a metal?

Hard and brittle
Lightweight and porous
Heavy and soft
Transparent and flexible

The correct answer is: Heavy and soft

Lead is characterized as heavy and soft due to its physical properties. As a metal, lead has a high density, which makes it feel heavy compared to many other materials. Specifically, lead has a density of about 11.34 grams per cubic centimeter, making it one of the heavier common metals. Additionally, lead is known for its relatively low hardness and malleability when compared to other metals. It can be easily cut and shaped, which contributes to its designation as being soft. These properties make lead suitable for various applications, such as in batteries, radiation shielding, and certain types of solder. Understanding these characteristics is important, particularly in contexts related to health and safety, as lead exposure can have severe effects on human health. The options that describe lead in other ways do not align with its actual properties. For instance, being lightweight and porous does not accurately portray lead's density and solidity, while being transparent and flexible is not typical of metals, which are generally opaque and tend to be rigid.
