The reaction is:
Te + O2 = TeO2
Te is the chemical symbol for tellurium, a metalloid element with atomic number 52.
When brass is heated, it can oxidize and change color. It typically starts as a golden-yellow color when cool, then turns to a darker brown or red color as it gets heated, and eventually may develop blue or greenish hues due to oxidation.
Tellurium
The most common isotopes of tellurium are tellurium-128, tellurium-130, tellurium-132, tellurium-128m, and tellurium-130m. These isotopes have varying numbers of neutrons in their nuclei, giving them different atomic masses.
Tellurium was the first name.
TeCl2 is the chemical formula for tellurium dichloride. It is a compound composed of tellurium and chlorine atoms. Tellurium dichloride is a yellow to red-brown solid that is used in the synthesis of various tellurium-containing compounds.
Tellurium is one of the Rare Earths.
The chemical symbol of tellurium is Te.
When silver is heated, it will expand due to the increase in temperature. At high temperatures, silver will oxidize and form a black layer of silver oxide on its surface. If heated further, silver will eventually melt at a temperature of 961.78 degrees Celsius (1763.2 degrees Fahrenheit).
Yes, tellurium is a metalloid.
The element with 52 protons is Tellurium, which has the chemical symbol Te. It is a metalloid with a variety of applications in industry and technology.
