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

Answer:

$1.4 * 10^{-10}$

Step-by-step explanation:

1.4 is 10 decimal places away from  0.00000000014

Answer 2

Answer:

The radius of an iron atom, $r=1.4\times 10^{-10}\ m$

Step-by-step 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 :

$r=x\times 10^y$

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 :

$r=1.4\times 10^{-10}\ m$

Therefore, this is the required solution.
