The approximate value of the radius of a hydrogen atom is 0.00000005 millimeters.
The approximation of the radius of a hydrogen atom, given as 0.0000000529177 millimeters, is 0.00000005.
To express the given number as an approximation, we look at the digits beyond the sixth decimal place and round them up if they are greater than or equal to 5, and round them down if they are less than 5.
The given number is 0.0000000529177. The digit in the seventh decimal place is 5, which is exactly 5. Therefore, we round up the sixth decimal place to get the approximation.
Hence, the approximation of the given number is 0.00000006.
