The two isotopes (or varieties) of the element uranium, U238 and U235 have slightly different weights due to different numbers of neutrons in the nucleus. But, they have the same atomic number (meaning they have the same number of protons in the nucleus and the same number of electrons bound to the nucleus). Because they have the same number of electrons, from a chemical point of view, they are identical: that is, they form the same kinds of bonds with other elements and they cannot be separated by chemical means.

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.
Depleted uranium is chemically thee same as natural uranium but?

Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What is uranium 235 when added to natural uranium?
Uranium-235 is not added to natural uranium, it is extracted from natural uranium by a process called enrichment.
