Naming of elementsBy Arvindcheenu

Ancient naming

of elements

Several elements' names have Anglo-Saxon language origins, including gold, iron, copper and silver.

The Latin names of these elements are commemorated in their atomic symbols, Au (aurum) for gold and Fe (ferrum) for

iron.

The Romans began the practise of element names ending in "-um," with Victorian scientists continuing the trend.

In his time, NEARLY 63 ELEMENTS WERE FOUND and categorized.
