Question

Relative abundance (in percentage) of 14 C isotope is (A) 1.1 (B) 2 × 10-10 (C) 2 × 10-4 (D) 2 × 10-5

Carbon has mainly three isotopes. C - 12, C -13 and C - 14 . C - 14 is a radioactive isotope of carbon and present in least quantity, i.e. near about (2 × 10-10) underset98.9 % 12 C underset1.08 % 13 C underset2× 10-10 14 C

Q. Relative abundance (in percentage) of $^{14} C$ isotope is

$1.1$

$2 \times 1 0^{- 10}$

$2 \times 1 0^{- 4}$

$2 \times 1 0^{- 5}$
