# How to compare the nuclear density of different elements if mass number and atomic number are given?

Asked by poojakamde3 8th October 2017, 11:04 AM
1. For finding density we need mass and volume of nucleus.
2. Mass number is given as 55.85u (this is mass number of iron nucleus) here "u" is atomic mass unit. And 1u = 1.660539 x 10-27 Kg .
3. Multiply 55.85 and 1.660539 x 10-27 you will get mass of iron nucleus in Kg.
4. Volume of sphere (nucleus is sphere) is given by  .Here,  ,   and A is atomic number.
5. Find the volume and use the formula for density as
6. Use same method for nucleus of any other element and see which nucleus have more density and which ones less. In this way you can compare nuclear density of different elements.
