Uranium and radium, and a number of others, are natural elements found in the
ground, and they are radioactive.
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
All these elements are natural, solid and radioactive.
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
All these elements are natural radioactive elements.
Studying residues of uranium ores, Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
Marie and Pierre Curie discovered that polonium and radium are natural radioactive chemical elements. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
Polonium and radium are discovered in wastes from uranium minerals, after uranium separation. The important radioactivity of these residues (without uranium) warned the two about the possible existence of other radioactive elements.

Uranium itself is a radioactive and toxic element. All the elements from the decay chain of uranium isotopes are also radioactive (ex.: radon, radium, etc.) excepting the final product, an isotope of lead.
