What else can I help you with?
What is the chemical element of thorium?
Thorium: natural chemical element, metal, solid, radioactive, actinoids family, period 7, atomic number 90, used in breeder reactors, etc.
What familly name is thorium in?
Thorium is a member of the actinoids family and is placed in period 7.
How much thorium-234 will remain after 2 half lives?
After 2 half-lives, 25% of the original amount of thorium-234 will remain. This is because half of the substance decays in each half-life period.
In what group and period cerium belong?
It is a lanthanide in period 6.
What are the actinides in the Periodic Table of Elements?
The actinide series is a group of elements in the periodic table that includes actinium, thorium, uranium, and all elements from atomic number 89 (actinium) to 103 (lawrencium). These elements are all radioactive and have similar chemical properties.
Why does Thorium belong on the periodic table?
All chemical elements are placed in the periodic table.
What is the family number of thorium?
Thorium is a member of the actinoids family; it is also placed in the period 7 of the periodic table of Mendeleev.
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 is the chemical element of thorium?
Thorium: natural chemical element, metal, solid, radioactive, actinoids family, period 7, atomic number 90, used in breeder reactors, etc.
What period does scandium belong to?
Period 4
What period does haydn belong to?
Classical period
What familly name is thorium in?
Thorium is a member of the actinoids family and is placed in period 7.
Does radioactive dating with isotopes of uranium and thorium provide an estimate of the bigning middle or end of the period of earths fomation?
The upper limit of uranium-thorium-230 dating is 500 000 years.
How Does radioactive dating with isotopes of uranium and thorium provide an estimate of the beginning middle or end of the period of Earth's formation?
The upper limit of uranium-thorium-230 dating is 500 000 years.
How Does radioactive dating with isotopes of uranium and thorium provide an estimate of the beginning middle and end of the period of earth formation?
The upper limit of uranium-thorium-230 dating is 500 000 years.
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.
