Which of the following is NOT a characteristic of lead?

Lead is characterized by several distinct properties, and understanding these properties is essential for identifying materials relevant in various contexts, including environmental science and engineering.

Lead is a gray metal known for its density and durability. It is soft and malleable, meaning it can be easily shaped and deformed without breaking. These properties are significant in applications such as battery manufacturing and construction materials.

Another important aspect of lead is its toxicity. Lead exposure can lead to serious health issues, including neurological damage, especially in children. This characteristic is critical in discussions about environmental safety and public health.

Flammability, on the other hand, is not a property that is associated with lead. Unlike organic materials or certain other metals, lead is not prone to catching fire or burning easily. This distinction highlights the material's stability and safety in situations involving heat or flames, particularly in contexts where combustion is a concern.

Thus, understanding these characteristics not only provides insight into lead's behavior and applications but also helps in recognizing what makes it distinct from other materials.
