The symbols for elements such as silver (Ag), gold (Au), and tungsten (W) do not match their English names because they are derived from their Latin or other language names. This practice dates back to the early days of chemistry when Latin was the universal language of science.
1. **Silver (Ag)**: The symbol Ag comes from the Latin word ‘Argentum’, which means silver.
2. **Gold (Au)**: The symbol Au is derived from the Latin word ‘Aurum’, meaning gold.
3. **Tungsten (W)**: The symbol W comes from the German name ‘Wolfram’, which is why tungsten is also known as wolfram in some languages.
Here are three additional examples:
1. **Sodium (Na)**: The symbol Na comes from the Latin word ‘Natrium’.
2. **Potassium (K)**: The symbol K is derived from the Latin word ‘Kalium’.
3. **Iron (Fe)**: The symbol Fe comes from the Latin word ‘Ferrum’.
These symbols reflect the historical and linguistic roots of the elements, providing a glimpse into the history of chemistry and the global nature of scientific discovery.
