Verified step by step guidance

1. Identify the type of elements given: C (Carbon), Se (Selenium), B (Boron), Sn (Tin), and Cl (Chlorine).
2. Recall that metals are generally good conductors of electricity due to their free-moving electrons.
3. Determine which of these elements is a metal.
4. Recognize that Sn (Tin) is a metal, while the others are nonmetals or metalloids.
5. Conclude that Sn (Tin) is the best electrical conductor among the given elements.

Key Concepts

Electrical Conductivity

Electrical conductivity is the ability of a material to allow the flow of electric current. This property is influenced by the presence of free-moving charge carriers, such as electrons in metals. Generally, metals exhibit high conductivity due to their atomic structure, which allows electrons to move freely, while nonmetals typically have lower conductivity.

Metallic vs. Nonmetallic Elements

Elements can be classified as metals, nonmetals, or metalloids based on their physical and chemical properties. Metals, such as Sn (tin) and Cl (chlorine), tend to be good conductors of electricity, while nonmetals, like C (carbon) and Se (selenium), are usually poor conductors. Understanding this classification helps in predicting the electrical behavior of different elements.

Comparison of Conductivity in Specific Elements

When comparing the electrical conductivity of specific elements, it is essential to consider their position in the periodic table and their metallic character. For instance, among the elements listed, Sn is a metal and is known for its good conductivity, while C can conduct electricity in certain forms (like graphite) but is generally less conductive than metals. This comparison aids in identifying the best electrical conductor among the given elements.
