Question

A carbon atom usually has 6 protons and 6 neutrons. Carbon-14 is a type of carbon with atoms that contain 6 protons and 8 neutrons. Carbon-14 can be used to find the age of certain fossils. Carbon-14 is an example of a(n)

A
positive ion.

B
negative ion.

C

Answer 1

Answer:

D: isotope

Explanation:

Answer 2

Carbon-14 demonstrates an

D). Isotope

• 'Isoptopes' are described as 'any of two or more forms of an element where the atoms have the same number of protons, but a distinct number of neutrons within the nuclei.'
• This leads the atoms of isotopes to have the same atomic number yet a distinct mass number.
• Since Carbon-14 contains an atomic nucleus of 8 neutrons along with 6 protons, it would be classified as an isotope.

Thus, option D is the correct answer.
