Question

The radius of a helium atom is a 31 PM. What is the radius in nanometers?

Answer 1

Answer:

Thus, the radius of the helium atom in nanometers is - 0.031 nm

Explanation:

Given that:-

The radius of the helium atom = 31 pm

Considering the conversion of length in pm to the length in nm as:-

1 pm = 0.001 nm

So,

Applying the above conversion factor in the radius of helium atom as:-

Radius = $31\times 0.001$ nm = 0.031 nm

Thus, the radius of the helium atom in nanometers is - 0.031 nm
