Heavy elements contain more protons, which repel each other due to their positive charge. Neutrons help stabilize the nucleus by adding nuclear binding energy without adding additional electrostatic repulsion like protons do. Therefore, heavy nuclei tend to have more neutrons to help balance out the increased number of protons.
In a nuclear reactor, heavy water is used as a neutron moderator. It slows down neutrons produced during nuclear fission to enhance the probability of additional fission reactions. Heavy water, with its extra neutron, is more effective at slowing down neutrons compared to regular (light) water.

Heavy water has a lower neutron absorption cross-section compared to light water, providing better moderation of neutrons in pressurized reactors. This enables the use of natural uranium as fuel, reducing the need for enrichment. Additionally, heavy water allows for better heat transfer properties and reduced corrosion in reactor components.
Heavy water, or deuterium oxide, is preferred as a moderator in nuclear reactors because it slows down neutrons effectively without absorbing them as much as normal water. This allows for a more efficient nuclear reaction by increasing the probability of interaction between neutrons and fuel atoms. Additionally, heavy water has a lower probability of triggering nuclear reactions compared to normal water, reducing the risk of accidents.
This is the function of the moderator, which may be heavy water, light water, or graphite
The nucleus is heavy because it contains protons and neutrons, which have relatively high mass compared to electrons.
Heavy atoms have more protons and neutrons in their nuclei compared to light atoms. This increases the nuclear charge and mass of heavy atoms, making them less stable and more prone to undergo radioactive decay.
Neutrons are considered heavy particles because they have a mass similar to that of protons. Neutrons are composed of three quarks (two down quarks and one up quark) held together by the strong nuclear force.
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.

Another word for "light" as in not heavy is "lightweight."
