I'm not an atomic physicist by any stretch, but atoms per unit area =
really doesn't compute (atoms don't distribute themselves nicely in =
"layers."). Probably the best approach is to define how thin a "slice" =
you want to look at, then calculate the number of atoms in that volume. =

Subject: [SI-LIST] Copper atom density
I am interested in determining the density of copper atoms per unit=20
cross sectional area, i.e. the average number of atoms at the cross=20
sectional area of a conductor.
It is given by various sources that the volumetric density of copper is =
between
8.37 10^28 and
8.5 10^28 atoms/meter^3
Is it as simple as taking the 2/3 root of this number (19.3=20
10^18/meter^2)? That seems logical but not necessarily realistic. I=20
think there is a better answer but I'm not sure how to approach it.
