Question

Calculate the radius of nucleus with atomic number 8 ? (Hint: r=Ro*A1/3
Ro=1.4*10-15

Answer 1

Radius of nucleus varies as R=R 0 (A) 1/3 , where R 0 =1.3 Fermi. What is the volume of Be 8 nucleus (approx) [A = atomic ANSWERRadius of nucleus is R=1.3×(8) 1/3 Fermi=2.6Fermi=2.6×10 −15 meter=2.6×10 −13 cmThe nucleus is supposed to be sphere so volume=(4π/3)R 3 =4.1866×(2.6×10 −13 ) 3 cubic centimeter(cc)or Volume =7.36
