None, no element beyond lithium can have a stable isotope with as few as 3 neutrons. If by some happenstance a uranium nucleus did form with as few as 3 neutrons (this would be U95) it would instantly burst apart in a flash of protons before it could even be detected.
isotope
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.
More than 99%of naturally occurring uranium is U-238. The valuable U-235 makes up less than 1% of uranium, and must be "enriched" in complicated processes.
The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons.Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. mneutrons + m protons.So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons.An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons.The difference is the 3 neutrons.
Uranium-235 has 143 neutrons; uranium-238 has 146 neutrons. Each isotope has a different number of neutrons.

You think probably to depleted uranium.Depleted uranium is uranium containing less than 0,2 % the isotope 235U.

Any gene; depleted uranium is uranium containing more than 99,8 % of the isotope uranium 238.
Uranium 234, 235 an 238 are all natural isotopes of uranium.Uranium 235- neutrons: 143- atomic mass: 235,043 929 918 ± 0,000 001 957- half life: 7,038.108 years- concentration in natural uranium: 0,7204 %- 235U is a fissile isotope
There are about 61 neutrons in silver. It actually has less electrons and protons than neutrons, since it only has 47 of them.
The isotope has 20 protons and 24 neutrons. This isotope is called calcium-44, and it is a stable isotope of calcium.
an isotope of germanium. There are 5 stable isotopes of germanium (70, 72, 73, 74, and 76), so with two less neutrons than these you could have these isotopes (68, 70, 71, 72, or 74) of which the isotopes 68 and 71 are radioactive.
