Technetium is the only element below uranium that does not exist on Earth. It is a synthetic (man-made) element produced in a particle accelerator. For many years, chemists knew that an element with atomic number 43 must exist, based on an empty spot in the periodic table.
The number of electrons technetium pertechnetate must gain if it is reduced to the ground state of technetium metal is: A. 7 B. 5 C. 2 D. 1 4. In the 99m Tc-mertiatide (99m Tc-MAG3) complex, technetiumâs oxidation state is changed and it acquires the following electronic configuration in the complex.
