Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3

Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3. It is not known naturally in 'pure' form. The fluoride minerals containing essential yttrium include tveitite-(Y) (Y,Na)6Ca6Ca6F42 and gagarinite-(Y) NaCaY(F,Cl)6. Sometimes mineral fluorite contains admixtures of yttrium.
Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.

Tellurium is a chemical element that has the symbol Te and atomic number 52

Tellurium is a chemical element that has the symbol Te and atomic number 52. A brittle, mildly toxic, silver-white metalloid which looks similar to tin, tellurium is chemically related to selenium and sulfur. Tellurium was discovered in Transylvania (today part of Romania) in 1782 by Franz-Joseph Müller von Reichenstein in a mineral containing gold and tellurium. Martin Heinrich Klaproth named the new element in 1798 after the Latin word for "earth", tellus.
Although several gold deposits contain tellurium minerals, the main commercial source for tellurium is as a by-product of copper and lead production. Tellurium is primarily used in alloys, foremost in steel and copper to improve machinability. Applications in solar panels and as a semiconductor material also consume a considerable fraction of tellurium production.
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.

How to Build a Tellurium Atom for a Science Project

Muller von Reichenstein discovered tellurium in 1782. It is commonly added to the copper and stainless steel to improve machinability. Tellurium atomic number is 52, and its atomic symbol is Te. It is between antimony and iodine on the periodic table of elements. You can build one as a science project for your kids easily while teaching them the atoms.

Use a ruler to the position half a foam ball 2 1/2-inch scale on the center of a square of 3/4-inch-thick plywood 12 inches. Glue the foam ball in place. This will be the core of your model of tellurium.
