As compared to ^ 12 C atom, ^ 14 C atom has: - Vidyadip

MCQ

As compared to ${ }^{12} \mathrm{C}$ atom, ${ }^{14} \mathrm{C}$ atom has:

A
Two extra protons and two extra electrons.
B
Two extra protons but no extra electron.
✓
Two extra neutrons and no extra electron.
D
Two extra neutrons and two extra electrons.

✓

Answer

Correct option: C.

Two extra neutrons and no extra electron.

${ }^{12} \mathrm{C}$ and ${ }^{14} \mathrm{C}$ 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, ${ }^{12} \mathrm{C}$ has $6$ protons, $6$ electrons and $6$ neutrons, whereas ${ }^{14} \mathrm{C}$ has $6$ electrons, $6$ protons and $8$ neutrons.
