[00:00:01]Inside nuclear reactors, atoms break apart. Among the fragments appears element 43, not primordial but created.

[00:00:12]In the 19th century, Dimmitri Mendelv saw the gap. He named it echanganesees, an element predicted before it existed.

[00:00:22]In 1937, Carlo Perier and Alio Segre bombarded malibdinum with duterons and created the first artificial element.

[00:00:33]Technium forms during uranium fish.

[00:00:36]Fragments like malibdinum 99 decay into technium, a product of nuclear transformation.

[00:00:43]The name comes from Greek. Technettos meaning artificial, a name that defines its origin.

[00:00:52]Technium exists in stars but on Earth it does not persist. Its isotopes decay faster than geological time.

[00:01:03]Technium sits in group seven, a transition metal with partially filled d orbitals. Its electrons define its chemistry.

[00:01:13]Technium is a dense silvery metal. It conducts electricity and forms crystallin structures. Its properties resemble neighboring transition metals.

[00:01:23]Chemically, technium is highly variable.

[00:01:26]Its most stable form is the protectate ion, an oxidizing species with defined geometry.

[00:01:33]Technium is inherently radioactive, emitting gamma radiation. Its nuclei transition to more stable states, releasing measurable energy. The most important isotope is technium 99M, a metastable state with a 6-hour half-life. Ideal for medical imaging.

[00:01:54]Technium compounds form stable ions in solution. These can influence corrosion processes, modifying electrochemical behavior.

[00:02:04]At extremely low temperatures, technium becomes superconducting.

[00:02:09]Its electrical resistance drops to zero, a quantum state of perfect conduction.

[00:02:15]Technium 99M is used in medical imaging.

[00:02:18]Its gamma emissions are detected externally, producing detailed internal images.

[00:02:24]Technium is produced in nuclear reactors used worldwide in medical diagnostic, an element created by science sustained by purpose.
