-

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.
