Question

It was observed in an experiment that the radius of an atom of element A is 0.0000063 m and that of an
atom of element B is 0.00000084 m. Find the ratio of the radii of an atom of element A to that of element
B.
(Express the ratio in the simplest form.)​

Answer 1

Radius of element A = 0.0000063 m

Radius of element B = 0.00000084 m

0.0000063/0.00000084 = 15/2

or 15:2

Answer 2

Answer:

Ratio of the radius of element A to radius of element B = 15 : 2

Step-by-step explanation:

Given radius of element A = 0.0000063

          radius of element B = 0.00000084

       for simple calculation multiply both values with $10^{8}$

        radius of element A = 0.0000063 × $10^{8}$ = 630

       radius of element B = 0.00000084 ×$10^{8}$ = 84

       [ multiplying both values with same value doesn't change relation between the original values }

 ratio of radius of A to B = 630 : 84

                                     = 210 : 28  ( divided by 3)

                                     = 105 : 14   (divide by 2)

                                     = 15 : 2      ( divided by 7)  

  the final ratio = 15 : 2
