Question

Density of nucleus is
(a) More for lighter elements and less for heavier elements
(b) More for heavier elements and less for lighter elements
(c) Very less compared to ordinary matter
(d) A constant

Answer 1

Answer:

b is the right answer

Explanation:

mark me as brainliest

Answer 2

Nucleus

d) constant

Nuclear density can be defined as the ration of mass of nucleus to the volume of nucleus. Nucleus density is constant . It is independent of the mass number or size of an atom. The average density of the nucleus of any atom is $2.304X10^{17} \ kg/m^3$.  Thus, the density of nuclear material is more than 2.1014 times greater than that of water. The atomic nucleus carries most of the atom mass and the atomic nucleus is very small in comparison.
