Discovery and Origin
Technetium was discovered in 1937 by Carlo Perrier and Emilio Segre, two Italian physicists who were studying the by-products of uranium. They observed a new radiation, which they called “technetium” after the Greek word technetos, which means artificial.
Technetium is a rare element, and it is not found naturally in the Earth’s crust. Instead, it is produced as a by-product of uranium and some other heavy metal ores.
Technetium is also produced in stars, where it is formed during supernova explosions.
Identification and Atomic Data
Technetium has an atomic number of 43, which means it has 43 protons in its nucleus. Its electron configuration is [Kr] 4d5 5s2, which indicates that it has five electrons in its d orbital and two in its s orbital.
Technetium has a unique atomic structure, with an unstable nucleus that can undergo radioactive decay. There are 28 known isotopes of technetium, ranging from technetium-85 to technetium-112, with technetium-99m being the most commonly used isotope.
Properties and Characteristics
Technetium is a silvery-gray metal that is highly reactive and can easily form compounds with other elements. It has a melting point of 2,156C and a boiling point of 4,265C.
Technetium has a density that is similar to that of platinum and is a good conductor of electricity. Technetium can exist in different oxidation states, ranging from -1 to +7, with the +7 state being the most stable.
Uses

Technetium is an element that is shrouded in mystery, and there are many interesting facts that you may not know about it. In this expanded article, we will delve deeper into some of the most fascinating aspects of technetium, including its symbol, production, and cost.
By the end of this article, you will have a greater appreciation for this unique element.
Symbol and Production
The symbol for technetium is Tc, and it is represented by a stylized human hand. The hand represents the fact that technetium was the first element that was artificially produced by scientists.
The hand symbol also represents the process of nuclear fission, which is used to produce technetium. The hand symbol is recognized worldwide as the symbol for technetium.
Technetium is produced by bombarding molybdenum with neutrons in a nuclear reactor. This process causes molybdenum to decay into technetium.
Once the technetium is produced, it is extracted from the reactor and purified for use in various applications. Technetium is used in many industries, including healthcare, electronics, and nuclear energy.
Cost
Technetium is a radioactive element, and it is costly to produce. The commercial availability of technetium is limited, and it is not widely available for purchase on the open market.
Technetium is typically sold to radiopharmacies, which use it to produce diagnostic imaging agents. The cost of technetium varies depending on the purity and the quantity purchased.
Generally speaking, technetium costs around $15,000 per gram, which makes it one of the most expensive elements on the planet. The high cost of technetium is due to the difficulties associated with producing and purifying it.
Technetium is a highly radioactive element, and it must be handled with extreme care. The production process is complex and involves the use of specialized equipment and procedures.
These factors contribute to the high cost of technetium. Interestingly, technetium is not found in nature, and it is only produced artificially.
This means that all the technetium that exists on Earth today has been created by humans. The scarcity of technetium also contributes to its high cost.
In the medical field, the cost of technetium is often covered by insurance companies, as it is a necessary component of many diagnostic imaging procedures. While the cost of technetium may be high, its benefits in healthcare outweigh the expense, as it can help diagnose and treat many medical conditions.
