24074 (Rh) atoms would have to be placed side by side to span a distance of 6.0.
The smallest piece of matter that exists in the universe is an atom. Atoms that are neutral or ionized make up every material in our environment. The atoms are tiny, spherical objects, and the Armstrong unit is used to measure their diameter.
1A = (10^-10)
The diameter of a rhodium atom (Rh) is approximately d = 2.7 x 10^-10
so,
It is assumed that if we keep n atoms next to one another, we will create a distance of L = 6.5μm = 6.5 x 10^-6
In this case,
We can see that if we keep the atoms side by side, the total length of them will be determined by adding the total diameters.
we have:
L = n d
n = L/d
Putting values :
n = (6.5 x 10^-6)/( 2.7 x 10^-10)
n = 24074
24074 (Rh) atoms would have to be placed side by side to span a distance of 6.0
