Question

In: Physics

the magnitude of the charge of the electron is

The magnitude of the charge of the electron is

  • (a) equal to F
  • (b) equal to F/NA
  • (c) equal to 2F/NA
  • (d) equal to NA/F
  • (e) none of these.

Solutions

Expert Solution

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).
