The radius of a potassium
atom is 0.227 nm. Express this
radius in the unit centimeters.

The radius of a potassium atom is 0.227 nm. In centimeters, the radius of potassium is 2.27 × 10⁻⁸ cm

Potassium is an element on the periodic table with the atomic number 19. It has white, lustrous, and shiny color. They exhibit a low melting point and are a great conductor of electricity.

Given that:

The radius of a potassium atom is 0.227 nm

Using the standard conversion analysis:

Since 1 nanometer (nm) = 1.0 × 10⁻⁷ centimeters (cm)

Then, 0.227 nm is:

=

= 2.27 × 10⁻⁸ cm

Therefore, we can conclude that the radius of a potassium atom in centimeters is 2.27 × 10⁻⁸ cm

0.227 nm can also be written as

0.227 * m

and we know that 1 cm = 1m * 100

so we will multiply by with 100:

0.227 * cm

2.27 * cm
