Marie Curie- Meagan Stephens

Marie Curie is known for her discovery of radioactivity. She conducted groundbreaking research on radioactive elements such as uranium and thorium, and identified the elements polonium and radium. Her work revolutionized the field of physics and earned her two Nobel Prizes, making her the first woman to receive this prestigious award. Curie's discoveries paved the way for advancements in nuclear science and radiation therapy, and her contributions continue to have a lasting impact on the scientific community.

Henri Becquerel was indeed a French physicist who conducted research on radioactivity. His work was influential in the field and inspired Marie Curie to further investigate this phenomenon. Therefore, it is correct to say that Curie based her research off of Becquerel's work.

Curie was not the second woman to ever win the Nobel prize. In fact, she was the first woman to win a Nobel prize, and she won it twice. In 1903, she won the Nobel prize in Physics along with her husband Pierre Curie and Antoine Henri Becquerel. Then in 1911, she won the Nobel prize in Chemistry for her discovery of the elements polonium and radium. So, the statement that Curie was the second woman to ever win the Nobel prize is false.

Curie's portable machine was nicknamed "Little Curie" because it was a smaller version of the X-ray machine developed by Marie Curie. The nickname likely emphasizes the machine's compact size and its association with Marie Curie herself.

Marie and her husband discovered "radioactivity" in pitchblende. Pitchblende is a mineral that contains high levels of uranium and radium, which are radioactive elements. Their discovery of radioactivity in pitchblende led to groundbreaking research in the field of nuclear physics and earned them a Nobel Prize in Physics.
