Why is graphite considered an elemental form of carbon?

• A. Graphite is a compound formed by the reaction of carbon with hydrogen.
• B. Graphite is composed entirely of carbon atoms arranged in a specific structure.
• C. Graphite is a mixture of carbon and nitrogen.
• D. Graphite contains both carbon and oxygen atoms in its structure.

Answer: (B)

Verified step by step guidance

1. Understand the definition of an elemental form: An elemental form consists of only one type of atom, without being combined chemically with atoms of other elements.
2. Recall that graphite is a form of carbon where all atoms are carbon atoms arranged in layers of hexagonal rings.
3. Recognize that graphite does not contain atoms of hydrogen, nitrogen, oxygen, or any other element; it is purely carbon.
4. Note that the properties of graphite arise from the specific arrangement of carbon atoms, not from the presence of other elements.
5. Conclude that graphite is considered an elemental form of carbon because it is composed entirely of carbon atoms bonded together in a particular structure.
