Hydrogen
This element is tellurium with a covalent atomic radius of 140 pm.
Selenium and tellurium are similar to sulfur.
Dmitri Mendeleev switched the positions of iodine and tellurium in his periodic table based on their properties, correctly predicting the existence and properties of missing elements.
Boron, silicon, germanium, arsenic, antimony, and tellurium are the metalloids.
THse elements are tellurium and iodine.
Tellurium typically forms covalent bonds. It can also form ionic bonds in certain cases.
Like almost all elements, tellurium can be solid, liquid, or gas, depending on its temperature and pressure.
It's technically an ionic bond because Al is a metal and Te is a non-metal; however, a low electronegativity difference between these two elements means the bond would have quite a bit of covalent character.
Berkelium can react with oxygen, sulfur, selenium, tellurium, carbon, nitrogen, hydrogen, chlorine, fluorine, bromine, phosphorus and very probable also with other elements.
Tellurium and Iodine
This element is tellurium with a covalent atomic radius of 140 pm.
Tellurium is radioactive, though there are stable isotopes. The radioactive isotopes found in nature account for more than two thirds of any normal sample. Additional synthetic radioactive isotopes exist.
Selenium and tellurium are similar to sulfur.
Dmitri Mendeleev switched the positions of iodine and tellurium in his periodic table based on their properties, correctly predicting the existence and properties of missing elements.
I don't bloody know mate!
Boron, silicon, germanium, arsenic, antimony, and tellurium are the metalloids.
