Uranium-235 and uranium-238 are natural, radioactive isotopes of uranium; they have 92 protons and electrons but the number of neutrons is different:
- for 235U: 143
- for 238U: 146
The are fuels: petroleum is a fossil fuel, uranium can be used as nuclear fuel.
Uranium and titanium are natural chemical elements, solid metals at room temperature.
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
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.
Uranium-235 has 143 neutrons, uranium-238 has146 neutrons.
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.

Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.

Uranium-235 is found in nature at about 0.7% concentration to uranium-238.
143 & 146
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
