Question

Out of c-12 and c-14 isotopes of carbon ,which is of radioactive nature?

Answer 1

Answer:

Explanation:

The nucleus of carbon 14 contains 6 protons and 8 neutrons, as opposed to the 6 and 6 found in ordinary carbon 12. The imbalance makes carbon 14 a radioisotope with a half-life of 5,700 years, and an emitter of beta particles. This radioactive isotope of carbon is called radiocarbon.

Answer 2

C-14 is radioactive.

• C-12 and C-14 are isotopes of each other they have the same atomic number but a different mass number.
• Among C-12 and C-14, the C-14 isotope is radioactive.
• C-12 has six electrons and six neutrons. So, it is a stable compound.
• C-14 has six electrons and eight neutrons. Thus these eight neutrons make the nucleus unstable.
• This unstable nucleus makes scratter radiation and becomes radioactive.
