Who discovered the physical properites of technetium?
The physical properties of technetium were determined after the war by different chemists and physicists around the world.
How were chemists able to predict the chemical properties of technetium?
Chemists were able to predict the chemical properties of technetium by studying the periodic table and observing trends in the elements around it. Technetium is located in the transition metals group, so it was predicted to have similar properties to other elements in that group with its 7 valence electrons. Additionally, its position in the periodic table suggested that it would exhibit variable oxidation states.
