The approximation of the radius of a hydrogen atom is 0.00000005 of a millimeter.
To express the radius of a hydrogen atom as an approximation, we can round the number to a reasonable number of significant figures. The correct approximation would be:
0.000000053
To express the given radius as an approximation, we can round it to a more manageable number while still preserving the significant digits.
The given radius is 0.0000000529177 mm. Rounded to an approximation with six significant digits, we get 0.000000053 mm or 5.3 x 10^-8 mm. Therefore, the correct approximation is 0.000000053 or 5.3 x 10^-8.
