Why the periodic table of elements some of them don't identify the symbol like silver gold iron?

Answer 1

There are a handful or elements whose chemical symbols do not match their English names. In most cases they are very familiar and common elements, and have symbols that match Latin names instead:

Sodium -- Na from Natrium, named after a strongly alkaline lake Natron

Potassium -- K from Kalium, same Arabic root word as alkali

Iron -- Fe from Ferrum

Copper -- Cu from Cuprum (or Cyprus)

Silver -- Ag from Argentum

Antimony -- Sb from Stibium

Gold -- Au from Aurum, and

Mercury -- Hg from Hydrargyrum -- liquid silver

There is one element whose symbol comes from its German name:

Tungsten -- W from Wolfram -- Wolf Rahm = wolf's breath. Our name for it comes from the Swedish Tung Sten = heavy stone.

Answer 2

Some elements have symbols that are derived from their English or Latin names, while others use symbols that relate to their old names or historical origins. For example, gold's symbol is "Au" from the Latin word "aurum," while iron's symbol "Fe" comes from the Latin word "ferrum." These symbols help to uniquely identify each element in a standardized way worldwide.
