2. Where was Frederick Soddy born?Tonder, Denmark
3. What is Frederick Soddy known for?Pioneering work in radiochemistry, explaining radioactivity as elemental transmutation, and discovering isotopes
4. What is the career?Radiochemist, physicist, and influential thinker in economics and finance
5. What did Frederick Soddy discover about elements?Frederick Soddy showed that elements can change into other elements through a process called transmutation, which happens during radioactivity.
6. Why is the term "isotope" important?He coined the word "isotope" to describe atoms of the same element that have different masses but act the same in chemical reactions.

Radiochemistry: The branch of chemistry concerned with radioactive materials and their properties.
Transmutation: The process by which one element is transformed into another, often through radioactive decay or nuclear reactions.
Isotopes: Atoms of the same element that have the same number of protons but different numbers of neutrons, leading to different atomic masses.
Nuclear Reactions: Processes involving changes to the nucleus of an atom, such as fission, fusion, or radioactive decay.
