Why do heavy elements neclei contain proportionally more neutrons than light element nuclei?

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 nuclear reactor heavy water is used as?

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.


Where are the heavy particles of an atom found?

in the nucleus (composed of protons and neutrons).


The advantage of heavy water as coolant over light water in pressurized reactors?

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 is preferred as a moderator over normal water?

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.

How can neutrons be slowed in the reactor core?

This is the function of the moderator, which may be heavy water, light water, or graphite


Is the nucleus light or heavy?

The nucleus is heavy because it contains protons and neutrons, which have relatively high mass compared to electrons.


What does the nuclei of heavy atoms have that light atoms do not have?

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.


Is aneutrons is a light partice or heavy?

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.


Are neutrons heavy in mass?

No, they're as heavy as protons.

Why iron is heavy while sodium is light?

The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.
