The radius of a hydrogen atom is 0.0000000529177 of a millimeter express this number as an approximate

Answer 1

To express the radius of a hydrogen atom, which is 0.0000000529177 millimeters, in a more manageable form, we can convert it into scientific notation.

The number in scientific notation is:

\[ 5.29177 \times 10^{-8} \text{ mm} \]

For an approximate value, you could round it to:

\[ 5.3 \times 10^{-8} \text{ mm} \]

Thus, the approximate radius of a hydrogen atom is \(5.3 \times 10^{-8}\) millimeters.
