Carbon Chemistry and Hierarchy of Matter

Front

What are isotopes of carbon?

Back

Isotopes of carbon are atoms of carbon that have the same number of protons (6) but different numbers of neutrons. Examples include carbon-12 (6 protons, 6 neutrons), carbon-13 (6 protons, 7 neutrons), and carbon-14 (6 protons, 8 neutrons).

What is a compound?

Back

A compound is a substance formed when two or more different elements are chemically bonded together. An example is carbon dioxide (CO2), which consists of carbon and oxygen.

Front

Which biological macromolecule stores genetic information?

Back

Nucleic acids, such as DNA and RNA, are the biological macromolecules responsible for storing and transmitting genetic information.

Front

Which substance does NOT contain carbon?

Back

Water (H2O) does not contain carbon, while lipids, proteins, nucleic acids, and carbohydrates all contain carbon.

Front

What is the smallest piece of carbon?

Back

The smallest piece of carbon is one atom of carbon.

Front

Define carbon chemistry.

Back

Carbon chemistry, or organic chemistry, is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds.

Front

What is the significance of carbon in biological systems?

Back

Carbon is essential for life as it is the primary component of biological macromolecules, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What are the four main types of biological macromolecules?

Back

The four main types of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

What is the atomic number of carbon?

Back

The atomic number of carbon is 6, which means it has 6 protons in its nucleus.
