How small is an atom. Write down the calculation.
The diameter of a US penny is 19 mm. The diameter of a silver atom, by comparison, is only 2.88 *10 -10mm.
How many silver atoms could be arranged side by side in a straight line at diameter of a penny (d penny)? 10 min
d penny =19mm I # Ag = d penny /d Ag atom I # Ag=19mm /2.88 *10 -10mm = 6.6*106 atoms
d Ag atom =2.88 *10 -10mm [ 6 600 000 atoms]
# Ag atoms--->? Atoms
