Question

The radius of a fluorine atom is about 5 x 10" millimeter. The radius of a strontium atom is about

2 x 10-7 millimeter.

About how many times larger is the radius of a strontium atom than the radius of a fluorine atom?

Answer 1

It will be 4 times larger.

Explanation:

The radius of a fluorine atom is about
`5 * 10^(- 8)` mm. and the radius of a strontium atom is about
`2 * 10^(- 7)` mm.

We have to calculate the number of times larger the radius of a strontium atom than the radius of a fluorine atom.

We will get the number by dividing the radius of a strontium atom by the radius of a fluorine atom.

Hence, it will be
`(2 * 10^(- 7) )/(5 * 10^(- 8)) = (20)/(5) = 4` times larger. (Answer)
