Question

the mass number of nuclei of two elements A and B respectively in the ratio 27:1. If the radius of nucleus of B is 2.4 × 10 to the power - 15 m, calculate the radius of nucleus of A

Plz answer it guys☺☺

And bye again ✌✌​

Answer 1

Answer:

As We can see from the ratio,,

A is aluminum

B is Hydrogen!

Consider A as R1 and B as R2

Now, We know that..

=R= R°A^1/3

therefore,

R1/R2 = (A1/ A2)^1/3

R1 = R2 (A1/A2)^1/3

now substituting the values from the question...!

R1 = 2.4x(27/1)^1/3 FermiMeter

R1 = 7.2fm!!

So A=7.2fm

Hope u got ur answer
