Polonium

Polonium

What is Polonium? Polonium is a post-transition metal in in group 16, period 6 of the periodic table. It is radioactive and very rare on Earth because it has no stable isotopes. However, the decay of uranium produces polonium, so polonium can be found in trace amounts in minerals that contain uranium. Polonium has few practical uses, though it has been used in atomic bombs, poison, and aerospace t... »

Neodymium

Neodymium

What is Neodymium? Neodymium is a soft, silvery metal within the lanthanide series of elements (elements 57-71). Therefore, it has similar chemical properties to lanthanides. It is a common element on Earth but is not found in its pure form. It is found in phosphate minerals that contain other lanthanides, including cerium, lanthanum, and samarium.   It has five stable isotopes and two radioisotop... »

Cesium

Cesium

What is Cesium? Cesium is a soft, silvery-golden alkali metal that is liquid just above room temperature. It is rare on Earth and is usually found in minerals that contain other alkali metals. Like all alkali metals, it is very reactive, and so does not exist in nature in its pure form. It only has one stable isotope and one radioactive isotope that exist in nature. Cesium is used to separate soli... »

Yttrium

Yttrium

What is Yttrium? Yttrium is a silvery metallic transition metal. It is the 39th element in the periodic table. It has similar chemical properties to lanthanides (elements 57-71 in the periodic table) and likewise, yttrium is also classified as a rare-earth element. Rare-earth elements are heavier than iron and are found in low concentrations in the environment. Yttrium is never found as a pure ele... »

Bismuth

Bismuth

What is Bismuth? Bismuth is a post-transition metal in group 15, period 6 of the periodic table. Pure bismuth is a solid, lustrous and silver in appearance. It has historically been used in medicine. It also has many current applications, including cosmetics, alloys, paint, and fireworks.   Bismuth’s Place in the Periodic Table Group 15 elements are known as pnictogens. Pnictogen is der... »

Francium

Francium

What is Francium? Francium is quite a unique element. It is the 87th element on the periodic table and is denoted by the symbol Fr. This element is extremely radioactive, it’s most stable isotope, francium-223 only has a half life of 22 minutes! Much about francium remains quite unknown, and scientists believe that many questions regarding this element may never actually be answered due to its nat... »

Tellurium

Tellurium

What is Tellurium? Tellurium is a silver-white metalloid and it is one of the rarest stable elements on Earth. Metalloids have properties that are between metals and non-metals. Tellurium is also a member of the group 16 elements, which are called chalcogens.   Tellurium’s Place in the Periodic Table Tellurium is a group 16 element in period 5. Group 16 elements are known as and include... »

Tantalum

Tantalum

What is Tantalum? At room temperature and pressure, tantalum is a shiny, silvery metal.  It is a transition metal and is therefore located with the other transition metals in the middle of the periodic table (the d-block). Tantalum is used in electronics, surgical implants, and applications that require resistance to corrosion.             Tantalum’s Place in th... »

Samarium

Samarium

What is Samarium? Samarium is a rare earth element of the lanthanide series, which are elements with atomic numbers from 57 to 71. It is a hard silvery metal. It has numerous applications in magnets, industrial chemical processes, cancer radiotherapy, and nuclear reactors.   Samarium’s Place in the Periodic Table Samarium is a lanthanide. Lanthanides, scandium and yttrium make a group o... »

Xenon

Xenon

What is Xenon? Xenon is a colorless, dense, and odorless gas. It is a member of group 18 elements, which are also known as the noble gases. Noble gases have very low reactivity. This makes them useful for applications where chemical reactions are unwanted. Xenon is found and obtained from the atmosphere. When voltage is applied across an electrode in xenon gas it produces a bright flash light, so ... »
