Example sentencesExamples - At higher temperatures, the metal does combine with many acids, the halogens, sulfur, selenium, and tellurium.
- Lead, tellurium and selenium are added to copper and its alloys to improve machinability.
- Like selenium, tellurium is used in electronic devices.
- Lead, selenium, tellurium and sulfur are added to copper alloys to improve machinability.
- Elements such as lead, tellurium, beryllium, chromium, phosphorus, and manganese have little or no effect on the corrosion resistance of coppers and binary copper-zinc alloys.
Origin Early 19th century: modern Latin, from Latin tellus, tellur- 'earth', probably named in contrast to uranium.
