Question 17

A carbon-14 (614C^{14}_{6}\text{C}614​C) nucleus is unstable and undergoes beta-minus decay.

What is the specific charge of a carbon-14 nucleus?

Use the following values:

  • Charge of a proton = 1.60 × 10-19 C
  • Mass of a nucleon = 1.67 × 10-27 kg
A

4.11×107 C kg−14.11 \times 10^7 \text{ C kg}^{-1}4.11×107 C kg−1

B

5.47×107 C kg−15.47 \times 10^7 \text{ C kg}^{-1}5.47×107 C kg−1

C

7.19×107 C kg−17.19 \times 10^7 \text{ C kg}^{-1}7.19×107 C kg−1

D

9.58×107 C kg−19.58 \times 10^7 \text{ C kg}^{-1}9.58×107 C kg−1
