Morphology

uranium-235 = uranium (semi-transparent) = uranium + 235

The form 'uranium-235' transparently indicates a specific isotope of uranium, but the technical properties implied by '235' (e.g., fissile behaviour) are specialized knowledge beyond general learners.

Etymology

Uranium-235 starts with uranium, which was named after the planet Uranus, so the element's name is like the planet's name. The 235 shows the particular type of uranium that has 235 tiny 'particles' in its center, and this type can split and release a very large amount of energy, which is why uranium-235 is used as fuel in nuclear reactors and in weapons.
