How many elements are natural in the periodic table?
90: The first 92 elements except technetium and promethium.
What is the symbol for Technetium on the periodic table?
Technetium has the symbol of Tc. It has the atomic number of 43.
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.
What period was technetium found in?
Technetium is in the period 5 of the periodic table.
What is the symbal for technetium on the periodic table?
The chemical symbol of technetium is Tc.
What group on the periodic table are synthetic elments?
Technetium (43), Promethium (61), and all the transuranic elements are synthetic.
Does technetium combine with other elements to form molecules?
Yes, technetium can combine with other elements to form molecules. Technetium has a tendency to form compounds with a variety of elements due to its position in the periodic table. Several technetium compounds have been synthesized and studied in both research and industrial applications.
What class is technetium?
Technetium is in the group 7, period 5 of the periodic table.
How many blank spaces did Mendeleev leave in the periodic table which represented elements that had not yet been discovered?
Mendeleev left gaps for eight elements in his periodic table that were yet to be discovered. These gaps eventually corresponded to the elements gallium, germanium, scandium, technetium, francium, and technetium.
Where does technetium come in the periodic table?
Technetium is placed in the group 7 (manganese group) and period 5 of the periodic table of Mendeleev. The atomic number is 43.
All of what element's isotopes are radioactive?
Technetium, Promethium, and all elements heavier than Bismuth.
