Respuesta :
Carbon - 14 is carbon's isotope that contains eight neutrons and six protons. It is formed by the collision of the atmospheric nitrogen with the neutrons in space. Thus, option B is correct.
What is carbon-14?
Carbon -14 has been known as the radioactive isotope of the carbon element with different atomic mass but has been constituted of the same atomic number.
The neutron in space collides with the nitrogen present in the atmosphere of the earth to undergo a transmutation reaction that can be shown as,
¹₀n + ¹⁴₇N → ¹⁴₆C + ₁¹H
Here, the atomic number or the number of the protons of carbon remains the same and is six, whereas the number of neutrons increases and becomes eight. This increases the atomic mass of the species.
Therefore, in option B. the neutrons collide with nitrogen to form carbon-14.
