Key Points: Classification of Elements
- Around 1800, only about 30 elements were known, whereas today the number has increased to 118.
- To manage the growing volume of information, scientists began identifying patterns in element properties to facilitate systematic classification.
- Elements were initially grouped as metals and nonmetals, and later, a third category called metalloids was recognised.
