What contains the bigger percentage of neutrons large nuclei or small nuclei?

Based on the extreme case of Hydrogen which has one proton and no neutrons for 0%, Large nuclei would have a larger percentage.


What Make up 50 percent of the atomic mass of the nucleus?

Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

How is the universe organized from biggest to smallest?

The universe is organized in a hierarchical structure from largest to smallest as follows: universe, observable universe, galaxy, solar system, planet, moon, and then down to subatomic particles like protons, neutrons, and electrons.


What percentage of thorium is in the universe?

Thorium constitutes about 4E-8% of the visible baryonic matter of the universe by mass. Visible baryonic matter is about 4.9% of the total mass of the universe, as per the latest estimates. So the mass-percentage of thorium in the universe would be 4E-8 x 0.049 = ... very little.

What does most matter in the universe exist in?

Most matter in the universe exists in the form of dark matter and dark energy, which are currently not fully understood by scientists. These two components make up the majority of the universe's mass-energy content, with ordinary matter (protons, neutrons, electrons) making up only a small percentage.
