Question

Find the no of electron present in -3C charge ​

Answer 1

Answer:

The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons. If the charge is negative, add the amount of charge to the atomic number to get the number of electrons.

No. of electron present in 1C = 6×10¹⁸ e

No. of electron present in -3C = -3×6×10¹⁸

= -18×10¹⁸
