Discovery of Elements

Subject: Chemistry

Book: General Chemistry

The discovery of elements spans centuries, from ancient metals (gold, silver, copper) to modern synthetic elements. Some were named after places (polonium, californium) or scientists (einsteinium, curium). Techniques like spectroscopy and particle accelerators continue to reveal new, highly unstable elements at the periodic table’s fringes. Each discovery expands our understanding of atomic structure, nuclear stability, and chemistry’s boundaries.
