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

0.118 nm

Step-by-step explanation:

Given,

The radius of the silicon atom =
`1.18* 10^(-8)\text{ cm}`

We know that,

1 centimeter =
`10^7` nanometer,

`\implies 1.18* 10^8\text{ cm}=1.18* 10^(-8)* 10^7=1.18* 10^(-8+7)=1.18* 10^(-1)\text{ nm}=0.118\text{ nm}`

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