Question
Choose the correct statement that defines transition elements.
- A transition element is one that forms cations with a completely filled d-subshell of electrons
- A transition element is one that forms at least one compound with a partially filled d-subshell of electrons
- A transition element is one that can speed up then the rate of chemical reactions in industrial processes
- A transition element is one whose compounds dissolve in water to form aqueous solutions which are colored
Hint:
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.
The transition elements are those elements that have partially filled penultimate d-subshells in their elementary form or in their commonly occurring oxidation states.
