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).
Uranium-238 decays into thorium-234 How do scientists explain why this happens?
This decay occurs due to the instability of the uranium-238 nucleus, which undergoes alpha decay to achieve a more stable configuration as thorium-234. During alpha decay, a helium nucleus (two protons and two neutrons) is emitted from the uranium-238 nucleus, leading to the transformation into thorium-234.
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.
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 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?
In beta decay of thorium-234, a neutron in the nucleus of thorium-234 is transformed into a proton, releasing an electron (beta particle) and an antineutrino. This process converts the thorium-234 nucleus into protactinium-234.
How many grams of Thorium-234 would be left after 96 days if there were 4 grams to start with?
After 96 days, there would be approximately 1 gram of Thorium-234 left from the initial 4 grams. Thorium-234 has a half-life of 24.1 days, so after each half-life, the amount of Thorium-234 would be halved.
When uranium undergoes alpha decay it becomes an isotope of thorium. Which notation indicates the thorium isotope produced?
When uranium undergoes alpha decay, it emits an alpha particle (which is equivalent to a helium nucleus, ( ^4_2He )), resulting in a decrease of its atomic number by 2 and its mass number by 4. For example, if uranium-238 (( ^{238}{92}U )) undergoes alpha decay, it transforms into thorium-234 (( ^{234}{90}Th )). Thus, the notation for the thorium isotope produced is ( ^{234}_{90}Th ).
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 %.
Thorium -234 proatinium-234 plus -1?
Thorium-234 does not decay into Protactinium-234. Instead, Thorium-234 naturally decays by alpha emission to Protactinium-230. The difference in decay modes is due to variances in their nuclear structures and energetics.
Thorium-234 atomic number 90 the number of neutrons 144 undergo beta decay what is the resulting element?
When thorium-234 undergoes beta decay, a neutron in the nucleus is converted into a proton, resulting in the formation of protactinium-234, with atomic number 91.
What does thorium-234 turns to after alpha and gamma emission?
Thorium-234 don't emit alpha particles.
What has the mass number of uranium-234?
The mass number of the isotope uranium-234 is 142.
How many days until one-sixteenth of a 54.2 g sample of thorium-234 remains?
The half-life of thorium-234 is about 24 days. Therefore, it would take approximately 96 days for one-sixteenth of the original 54.2 g sample of thorium-234 to remain.
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
