# Electron Charge

Hello all,

I have a queation, by using metal units, what is the unit of electrostatic charge?

Thanks,

One elementary charge.

Hi,
Thanks for the reply.
by “charge = multiple of electron charge (1.0 is a proton)” , Does it mean for example for 10 electron the charge should be set to -10?

Thanks,

I don’t understand this question. The charges would be determined from your force field parameterization.

Dear Axel,

Let me clarify, in codding Lammps, for metal units, what is the unit of charge ?
In the documentation it is said :
For unit metal;
charge = multiple of electron charge (1.0 is a proton)

Actually I didn’t exactly get what it means, may you know?

This is not a clarification. You are just repeating the same question. Thus the answer is the same.

For unit metal;

charge = multiple of electron charge (1.0 is a proton)

It is such a trivial matter, I don’t know any other way to explain it.
