It is for this reason that large nuclei contain proportionally more neutrons than light elements
in the nucleus (composed of protons and neutrons).
When they contain an excess of neutrons
Heavy water is used in nuclear reactors as moderator for neutrons.
it is heavy
It is for this reason that large nuclei contain proportionally more neutrons than light elements
This is the function of the moderator, which may be heavy water, light water, or graphite
No, they're as heavy as protons.
The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.

The nuclei of heavier atoms simply have more neutrons and protons than do lighter atoms.
