Heavy elements generally contain more neutrons than protons. This is because as the number of protons increases in heavier elements, the strong nuclear force needs additional neutrons to help offset the repulsive forces between the positively charged protons. This results in a higher neutron-to-proton ratio in heavier elements compared to lighter ones.

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.
What is neutron star crust made of?
The crust of a neutron star is primarily composed of heavy elements like iron and nickel. As the star cools, these elements solidify into a solid lattice structure. Additionally, the crust may also contain other materials like silicon and magnesium.
When are heavy nuclei most stable?
Heavy nuclei are most stable when their neutron-to-proton ratio approaches 1. Nuclei with too many or too few neutrons compared to protons will have higher instability. This balance contributes to stability by preventing the repulsion between protons from overpowering the attractive nuclear force.
Can Heavier elements like gold and uranium cannot be created in supernovae?
Heavier elements like gold and uranium are primarily formed in explosive events such as supernovae, but they are more significantly produced through a process called neutron capture during neutron star mergers. While supernovae do contribute to the synthesis of certain heavy elements, the extreme conditions and neutron-rich environments found in neutron star collisions are more conducive to creating the heaviest elements. Therefore, while supernovae play a role, they are not the sole site for the creation of all heavy elements.
Which two particles each have a mass approximately equal to one atomic mass unit?
The proton and the neutron each have a mass approximately equal to one atomic mass unit.

Radioactive elements include all those elements whose nuclei contain what?
Radioactive elements include all elements whose nuclei either:contain protons more than 83 proton, orcontain neutron to proton ratio out of the stability ratio.refer to related question below.

What is smaller nucleaus or neutron?
Since a nucleus contains from 1 (heavy hydrogen) to 150 neutrons, as well as up to 110 protons, the neutron is smaller.
Name the property of heavy water?
Heavy water contain deuterium, a hydrogen isotope having one neutron.

Where did the heavy elements in planetary objects originate?
The heaviest elements come mainly from supernovae. Iron is the heaviest element that can be produced by fusion. Heavier elements are produced by neutron capture. An individual free-floating neutron collides with a nucleus and merges with it. That doesn't produce a higher element on the periodic table, because the atomic number depends on the number of protons. However, nuclei with too many neutrons are unstable, and will eventually "decay". A neutron will decay into a proton and an electron. Free neutrons don't exist in great numbers in normal stars, so neutron capture doesn't happen significantly in them. Elements from carbon to iron can be formed by fusion in large stars.
How many elements in 'heavy' water?
Formula of heavy water is D2O. O is oxygen, D is deuterium - a hydrogen isotope having 1 proton and 1 neutron.
Do atoms split?
Yes, atoms can split in a process called nuclear fission. This usually occurs in heavy elements when they absorb a neutron and split into smaller elements, releasing a large amount of energy in the process. This phenomenon is the basis for nuclear power plants and atomic bombs.
Why is lead and Mercury called heavy metal?
This is because heavy metals are those metals having a neutron is to proton ration equal to or greater than 1.5Lead has 82 protons and 125 neutronsn/p=125/82=1.52Mercury has 80 protons and 121 neutronsn/p=121/80=1.51Hence lead and mercury are heavy metals
Which two particles each have a mass approximately equal to one atomic mass unit?
