The correct approximation is 0.00000005.
The correct approximation of the radius of a hydrogen atom would be 0.000000053.
To express the given number as an approximation, we need to round it to a more concise value. In this case, the original number is 0.0000000529177.
To round this number, we first look at the digits after the seventh decimal place. Since the digit after the seventh decimal place is 5, we round the number to the nearest eighth decimal place.
Checking the digit after the eighth decimal place, which is 2, we observe that it is less than 5. Therefore, we simply drop all the digits after the eighth decimal place, resulting in the approximation: 0.00000005.
