Alpha decay of Uranium-235 (²³⁵U) involves the emission of an alpha particle, which consists of 2 protons and 2 neutrons. When ²³⁵U undergoes alpha decay, it transforms into Thorium-231 (²³¹Th) while releasing an alpha particle (⁴₂He). This process reduces the atomic number from 92 to 90 and the mass number from 235 to 231. The equation for this decay can be written as: ²³⁵U → ²³¹Th + ⁴₂He.

What type of particle is emitted when U-235 decays to Np-235?
It is the reverse: Np-235 decay to U-235 by electron capture.
What isotope is formed when uranium 235 emits an alpha particle?
You get this answer by performing the following: Mass # Mass # 4 Atomic # Parent symbol -> Atomic # Daughter symbol + 2 He 238 234 4 92 U -> 90 Th + 2 He Both sides must equal the same thing, so if you figure out what plus 4 = 238 and what plus 2 = 92, you can figure out the element is formed through decay. The resulting element in this case is Thorium.
An isotope of uranium using nuclide notation?
The chemical symbol of uranium is U.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
What is the correct order of nuclear decay mode for the changes from U-238 to U-234?
The correct order of nuclear decay mode for the changes from U-238 to U-234 is alpha decay followed by beta decay. In alpha decay, the nucleus emits an alpha particle, reducing its atomic number by 2 and mass number by 4, resulting in Th-234. This is followed by beta decay, where a neutron is converted into a proton, producing U-234.

What is a good decay equation for uranium decay's to alpha decay?
The decay equation for uranium-238 (U-238) decaying into an alpha particle (helium-4) can be represented as follows: (^{238}{92}\text{U} \rightarrow ^{4}{2}\text{He} + ^{234}_{90}\text{Th}). This equation shows the radioactive decay process of U-238 into an alpha particle and thorium-234.

What is the equation for the alpha decay of uranium -237?
The equation for the alpha decay of 233Pu:94233Pu --> 92229U + 24He2+where the alpha particle is represented as a helium nucleus.Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.

How many protons and electrons in uranium 235?
Uranium-235 has 92 protons and 92 electrons. This is because the number of protons in an atom is equal to its atomic number, which is 92 for uranium. The number of electrons is also equal to the number of protons in a neutral atom.
What is the correct order of nuclear decay mode for the changes from U-238 to U-234?
The correct order of nuclear decay mode for the changes from U-238 to U-234 is alpha decay followed by beta decay.
