Elements were originally named after places, countries, continents, scientists, planets, and satellites. For example, polonium was named after Poland, curium was named after Marie Curie, and chromium comes from the Greek word for color. Element symbols are short representations of their names, with the first letter used for many elements like C for carbon and O for oxygen. Some elements use multiple letters from their name like Ca for calcium. A few element symbols come from their Latin names, such as Na for sodium and Fe for iron. Common elements used in daily life include iron, oxygen, carbon, aluminum, copper, nickel, gold, and silver.
