Question

If the radius of silicon atom is 1.18 x 10 -8 Cm , what is the radius in nm ?

Answer 1

The answer is .118 nm

Answer 2

Answer:

0.118 nm

Explanation:

Given,

The radius of the silicon atom = $1.18\times 10^{-8}\text{ cm}$

We know that,

1 centimeter = $10^7$ nanometer,

$\implies 1.18\times 10^8\text{ cm}=1.18\times 10^{-8}\times 10^7=1.18\times 10^{-8+7}=1.18\times 10^{-1}\text{ nm}=0.118\text{ nm}$

Hence, the radius of the silicon atom would be 0.118 nm
