These discoveries are examples of hard work, scientific passion, intelligence, patience etc.
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
Polonium
she discovered radium and polonium
The discovery (not invention) of polonium and radium didn't changed the history.
The discoveries of radium and polonium doesn't affect the atom model.
The Curies discovered two radioactive elements: polonium and radium.
Marie Curie
Radium was more or less discovered by accident while the Curies were looking for Uranium in samples of Pitchblende. In 1898, they discovered in tiny amounts, Polonium in July, and Radium in December.
Marie Curie's greatest contribution was her pioneering research on radioactivity. She discovered the elements polonium and radium and developed the theory of radioactivity, which revolutionized the field of nuclear physics. Her groundbreaking work laid the foundation for modern advancements in medicine, industry, and technology.

Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. 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.
Her husband, Pierre Curie, worked with Marie Curie when they discovered Polonium. The Curies also discovered that Thorium, discovered in 1829 by Jöns Jakob Berzelius, emits radiation.
