The magnitude of the charge of the electron is

- (a) equal to F
- (b) equal to F/
*N*_{A} - (c) equal to 2F/
*N*_{A} - (d) equal to
*N*_{A}/F - (e) none of these.

The relation between a faraday of charge of one atom of a univalent substance \((F),\) atom per

mole \(\left(N_{\mathrm{A}}\right)\) and the particle charge \((e)\) is \(F=N_{\mathrm{A}} e\)

Rearrange the above equation for the charge of electron

\(e=\frac{F}{N_{\mathrm{A}}}\)

So, the correct answer is option (b).
