Technetium, the first artificially produced element used in many medical diagnostic imaging scans, is found in which group of the periodic table?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Group 7.

  • Technetium, the first artificially produced element used in many medical diagnostic imaging scans, is found in Group 7 of the periodic table.

  • Technetium, represented by the symbol Tc, holds the atomic number 43 on the periodic table.

  • The elements of group 7 are called transition metals and they have similar properties.

  • Technetium is the lightest element for which every known isotope is radioactive, with none remaining stable — except for the fully ionised form of isotope ⁹⁷Tc.

  • This silvery-gray metal, which visually resembles platinum, is typically obtained as a fine gray powder.

  • The Technetium element was first identified in 1937 by scientists Carlo Perrier and Emilio Segrè.
