What is the diameter of a cadmium atom in Angstroms?

This may or may not be an odd unit of measurement for atomic sizes,
but I'm trying to get an idea of the relative size between the two.

An angstrom equaling 1 x 10-8 centimeters, which would equal routhly
.00000004 inches (if my math isn't too shot).

Please correct any errors.
Thanks,
Patrice

Hi!!


Let me start with the following definitions:
The atomic radius is the distance from the atomic nucleus to the
outmost stable electron orbital in an atom that is at equilibrium and
it is measured in picometers or angstroms.

The van der Waals radius of an atom is the radius of an imaginary hard
sphere which can be used to model the atom.


For the Cadmium the above values are (in picometres -pm):
Atomic radius (empirical) ---> 155 pm 
Atomic radius (calculated) --> 161 pm 
Van der Waals radius --------> 158 pm 


For practical purposes you can consider the Cadmium atom diameter as twice the 
Van der Waals radius, that is:
Cadmium atom diameter ------> 2*158 pm = 316 pm

Since each Angstrom is equivalent to 100 pm we have that:
Cadmium atom diameter ------> 316 pm = 3.16 A aprox.

Interesting, thorough answer.
Thanks, Patrice.

Dear patrice29, thank you so much for the good rating and comments,
and of course for the generous tip.

As far as I know the answer is correct including "Since each Angstrom
is equivalent to 100 pm"
An anstrom = 10-8 centimeters = 10-10 meters
A picometer is 10-12 meters 
100 picometers = one angstrom unit
