How many electrons are in thorium?
Thorium, with the chemical symbol Th, is the chemical element with the atomic number 90.
What is the isotope notation for thorium?
Unfortunately WikiAnswers doesn't accept subscript/superscript.For the isotope thorium-232: 232Th90232 is a superscript (mass number) and 90 is a subscript (atomic number).
How much of a 100 g sample of thorium 234 will be unchanged after 48.2 days?
After 48,2 days the amount of Th-234 will be 25 g.
How many electrons does Thorium have?
Thorium, or Th, has an atomic number of 90. That means that every atom of thorium has 90 protons. The only naturally abundant isotope of thorium is 232Th, and so therefore it has 232 - 90 = 142 neutrons.
When uranium-238 is transformed into thorium-234 it is represented by a balanced equation What is missing from the equation of U-238 undergoing radioactive decay?
alpha
How many electrons are in thorium?
Thorium, with the chemical symbol Th, is the chemical element with the atomic number 90.
Can two atoms become isotopes if they have the same mass number?
Yes, it is possible; example for the mass number 234:- uranium-234: 92 protons + 142 neutrons- thorium-234: 90 protons + 144 neutrons
What is beta decay of thorium 234?
Protactinium 234 is a decay product of thorium 234; the nuclear reaction is: 23490Th-----------beta rays-------------23491Pa
How many grams of Thorium-234 would be left after 96 days if there were 4 grams to start with?
This mass of Th-234 will be 0,25 g.
How much mass remains in Thorium 234 after a half?
After 24,10(3) days (the half-time of this isotope) the mass is 50 %.
What does thorium-234 turns to after alpha and gamma emission?
Thorium-234 don't emit alpha particles.
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
Thorium -234 proatinium-234 plus -1?
Protactinium 234 is a decay product of thorium 234; the nuclear reaction is: 23490Th---------------23491Pa + beta rays (e-)
What has the mass number of uranium-234?
The mass number of the isotope uranium-234 is 142.
Thorium-234 has a half life of about 24 days of a sample that originally contained 100 grams of thorium-234 now only contains 25 grams.what is the age of the sample?
25 grams of Thorium-234
How is thorium 234 changed into uranium 234?
Thorium-234 is not changed in uranium-234.- Th-234 is a decay product of U-238- By beta decay Th-234 is transformed in Pa-234
Why mass of uranium destroys when it breaks into platinum and then into thorium?
- After alpha disintegration the isotope uranium-238 is transformed in the isotope thorium-234. - After alpha disintegration the isotope uranium-235 is transformed in the isotope thorium-230. Platinum is a misspelling ?
