When uranium -238 decays to form thorium-234 the uranium nucleus emitts?
Uranium 238 is aan alpha particles emitter: halflife 4,468.109 years, energy 4,270 MeV.
Uranium -238 undergoes alpha decay Therefore uranium -238 will?
Uranium 238 is transformed in thorium 234 by alpha decay.
What family is uranium-238 in?
Uranium is a member of the actinoids family elements. Uranium-238 is a natural isotope of uranium.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Enriched uranium uranium 235 or uranium 238?
Enriched uranium is still usually mainly 238U, but it has a higher percentage of 235U than the natural abundance. Depleted uranium is exactly the opposite: it's got a LOWER than normal amount of 235U.
When uranium -238 decays to form thorium-234 the uranium nucleus emitts?
Uranium 238 is aan alpha particles emitter: halflife 4,468.109 years, energy 4,270 MeV.
Does uranium 238 have the shortest half life?
The half life of 238U is 4,468.109 years; this is a very long halflife !
What are the similarities and differences between the isotopes uranium-235 and uranium-238?
Uranium-235 and uranium-238 are the isotopes of the same element - uranium, a natural radioactive chemical element; the atomic number is the same - 92. Also the electronic structure, the number of protons, etc. Differences: atomic mass, number of neutrons, U-235 is fissile with thermal neutrons but U-238 is only fertile, halflife, type of disintegration types and energy of emitted radiations, etc.
What is the halflife of Uranium-239?
The half-life of uranium-239 is 23.45 minutes.
Does Uranium 238 and 235 release neutrons in nature as they do in a fission process?
Yes, by spontaneous fission, but the nymber of neutrons is very small because the halflife of the spontenuoes fission is: for Uranium 235: (1,0 ± 0,3).1019 years for Uranium 238: (8,20 ± 0,10).1015years

How many neutrons are stuffed into the nucleus of uranium-238?
Uranium-238 has 146 neutrons.
How many neutrons in a neutrally charged uranium 238?
Uranium 238 has 146 neutrons.
In Uranium-238 and Uranium-234 does neither element have a charge?
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.
