The approximation of the radius of a hydrogen atom is 0.000000053
The radius of a hydrogen atom, 0.0000000529177 millimeters, can be rounded to the nearest value as 0.00000005 millimeters.
To express the given radius of a hydrogen atom as an approximation, we need to consider the decimal places in the given number. The given radius is 0.0000000529177 millimeters.
Looking at the decimal places, the first non-zero digit is 5, which is located at the 8th decimal place. Therefore, we need to round the number to the appropriate decimal place.
Since the digit after the 8th decimal place (1) is less than 5, we round down. Rounding down means that we keep the digit at the 8th decimal place (5) and remove all the digits after it.
So, rounding the number 0.0000000529177 to the appropriate decimal place gives us the approximation as 0.00000005 millimeters.
