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 = [tex]31\times 0.001[/tex] nm = 0.031 nm
Thus, the radius of the helium atom in nanometers is - 0.031 nm
