The existence of radiation was discovered in 1896 by Henri Becquerel in the course of experiments involving uranium salts, though the nature of it was unknown.

The nature of the alpha particle was discovered by Ernest Rutherford, and he showed it was essentially an helium nucleus in 1907.

What is the radioactive decay process of U-238?

Uranium 238 breaks down into a series of radioactive products formed by giving off radiation. Uranium-238, Thorium-234, Protactinium-234, and Uranium-234 are the first 4 in the series.


Is radioactive uranium positively charged?

No, uranium is not positively charged. Uranium is a chemical element with a neutral charge due to an equal number of protons and electrons. However, some isotopes of uranium are radioactive, meaning they can emit radiation as they undergo radioactive decay.


What is the first radioactive element that forms when uranium 238 decays?

The first radioactive element formed when uranium-238 decays is thorium-234. Uranium-238 undergoes alpha decay to form thorium-234.
