Answer: -
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
Explanation: -
The mass number for ¹³C = 13
The atomic number for ¹³C = 6
Number of electrons present in ¹³C = atomic number = 6
Number of protons present in ¹³C = atomic number = 6
Number of neutrons present in ¹³C = mass number - atomic number = 13 - 6 = 7
For ¹³C ⁻ ion,
Number of electrons present = 6 + 1 = 7
Thus ¹³C ⁻ ion has 7 electrons, 7 neutrons and 6 protons.
