MCQ
As compared to 12C atom, 14C atom has:
- ATwo extra protons and two extra electrons.
- BTwo extra protons but no extra electron.
- CTwo extra neutrons and no extra electron.
- DTwo extra neutrons and two extra electrons.
✓
Answer
- Two extra neutrons and no extra electron.
Explanation:
12C and 14C are the two isotopes of carbon atom that have same atomic number, but different mass numbers. This means that they have same number of protons and electrons, but different number of neutrons. Therefore, 12C has 6 protons, 6 electrons and 6 neutrons, whereas 14C has 6 electrons, 6 protons and 8 neutrons.
