Show that nuclear density is almost constant for nuclei with Zgt10. |
|
Answer» Solution :Nuclear density, `rho` = (mass of the nuclei)/(VOLUME of the nuclei) = `(A.m)/((4)/(3) pi R_(0)^(3)A) = (m)/(4/3 pi R_(0)^(3))` `rho = (1.67 xx 10^(-27))/(4/3 pi xx (1.2 xx 10^(-15))^(3)) = 2.3 xx 10^(17) kg m^(-3)` The EXPRESSION shows that the nuclear density is independent of the mass number A.In other words, all the nuclei `(Z gt 10)` have the same density and it is IMPORTANT characteristics ofthe nuclei. |
