Question

The radius of an iron atom has been calculated to be about 0.00000000014 m. What is this length in scientific notation?

Answer 1

`1.4 * 10^(-10)`

Explanation:

1.4 is 10 decimal places away from 0.00000000014

Answer 2

The radius of an iron atom,
`r=1.4* 10^(-10)\ m`

Explanation:

Here, we need to write the radius of an iron atom in scientific notation. It is a way to express any number in easy manner.

The radius of iron is given as, r = 0.00000000014 m

A number can be written in scientific notation as :

`r=x* 10^y`

Where

x is any real number

and y can be any integer

There are 9 zeros before 14. In scientific notation it is written as :

`r=1.4* 10^(-10)\ m`

Therefore, this is the required solution.
