Final answer:
The diameter of a hydrogen atom is about 10 nm, 0.01 mm, or 10,000 µm. These conversions use scientific notation and knowledge of metric prefixes.
Step-by-step explanation:
The diameter of a hydrogen atom is about 10 nm (nanometers), which is also 10 x 10-9 meters or 1 x 10-8 meters. In other units, this translates to:
- 0.01 millimeters (since 1 mm = 10-3 meters)
- 10,000 micrometers (since 1 µm = 10-6 meters)
Using scientific notation and understanding unit prefixes greatly simplifies the comparison and conversion of such small dimensions like the diameter of a hydrogen atom.
