Answer

The diameter of 1 atom is 10nm.

Work Step by Step

100,000,000 atoms make a row equal to 1 cm $100,000,000 atoms = 1 cm$ Divide 1 cm by 100,000,000 so you can get 1 atom by itself $1 atom = \frac{1}{100,000,000} cm$ 1 divided by a billion is 1 nm $\frac{1}{1,000,000,000} cm = 1 nm$ $1 atom = 10 nm$
