Question

\Based on the reading, what are the properties of carbon-14? Check all that apply. Carbon-14 is a naturally occurring carbon isotope. Carbon-14 has a known half-life. Carbon-14 decays completely within 1,000 years. Carbon-14 is not radioactive. Carbon-14 is present in all living organisms.

Answer 1

Carbon-14 is a naturally occurring carbon isotope. Carbon-14 has a known half-life. Carbon-14 is present in all living organisms.

Answer 2

An isotope is the same atom with different number of neutrons in the nucleus. Carbon- 14 is a naturally occurring carbon isotope. It has a known half-life. It is present in all living organisms.

Isotopes of Carbon:

An isotope is the same atom with different number of neutrons in the nucleus. Carbon has 3 isotopes C-12, C-13 and C- 14.

Carbon-14:

• It is a naturally occurring (one parts per trillion) isotope.
• It is radioactive, It has a half- life of 5,700 years.
• It is found in all living organisms hence used for Carbon dating.

Hence, we can conclude that Carbon- 14 is a naturally occurring carbon isotope. It has a known half-life. It is present in all living organisms.
