  1. A transition element is one that forms cations with a completely filled d-subshell of electrons
  2. A transition element is one that forms at least one compound with a partially filled d-subshell of electrons
  3. A transition element is one that can speed up then the rate of chemical reactions in industrial processes
  4. A transition element is one whose compounds dissolve in water to form aqueous solutions which are colored

hintHint:

A transition element is onethat forms atleast one compound with a partially filled d-subshell of electrons

The correct answer is: A transition element is one that forms at least one compound with a partially filled d-subshell of electrons


    The transition elements are those elements that have partially filled penultimate d-subshells in their elementary form or in their commonly occurring oxidation states.
