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 is thorium smell like?
Thorium itself is odorless in its natural state. However, thorium compounds may have a slight metallic or musty odor. It is always important to handle thorium with proper precautions due to its radioactive properties.
What is the name of thorium ore?
Some thorium ores are monazite, thorianite, thorite.
Does thorium have multiple names?
Thorium is generally known by its chemical name "Thorium." However, it may also be referred to as "Th" on the periodic table.
What is the charge on the ion of thorium?
Thorium is a tetravalent element (4+).
Is thorium a solid or a liquid or gas?
Thorium is a solid metal.
When did thorium come on this earth?
Thorium is a natural chemical element; chemical elements were formed by stellar nucleosynthesis at the beginning of the universe.
What is the origin of thorium?
Thorium is a natural chemical element formed by stellar nucleosynthesis during the early stages of the Universe. Thorium exist in many minerals as monazite, thorianite, thorite.
What is the percentage of thorium in clay soil that is absorbed into the body?
When not mixed with clay, about 0.02% (depending on the type of thorium compound)of ingested Thorium is absorbed into the body but since Thorium is strongly adsorbed by clay, the absorption of ingested Thorium mixed with clay soil is negligible, much less than 0.02%.
What is the percentage of Thorium on earth?
The abundance of thorium in the Earth crust is approx. 12 ppm.
Which element would be most common in the universe sulfur or thorium?
Sulfur is of course more common.
What is the main source in the universe for the origin of the polonium?
Polonium isotopes are decay products of thorium or uranium.
What is the common compound of thorium?
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
What percentage of the universe is made of plasma?
99.999% of the universe is made of plasma
What is the rarest element in the universe?
Astatine is considered one of the rarest naturally occurring elements in the universe. It is part of the halogen group and is typically found in trace amounts in uranium and thorium ores.
What chemicals are in thorium fluoride?
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
Common commpouds of thorium?
Hazards and Health Considerations: Thorium presents both a toxic and radiological hazard. Toxicologically, it causes heavy metal poisoning similar to lead or the uranium isotopes. Biologically, thorium accumulates in the skeletal system where it has a biological half-life of 200 years, the same as plutonium. An M 17 protective mask and standard anti-contamination clothing will adequately protect against thorium.
What percentage of the universe has life?
that is unpredictable. cause we cant find the size of the universe....
