For each question, determine whether statement I is true or false and whether statement II is true or false. Select the appropriate answer combination from the choices below. Choices with a filled CE oval denote that statement II is a correct explanation of the true statement I.
|An element that has the electron configuration is a transition element||
||in atoms of transition elements, the , , , , and orbitals are completely filled in the ground state.|
Select an Answer
The correct answer is T, T.
The element with the electron configuration shown is vanadium (atomic number = ). The transition elements are those in groups 3-12 (or groups , depending on how a particular periodic table is labeled). Therefore, statement is true. It is also true that the , , , , and orbitals are completely filled in the transition elements. However, statement is not a correct explanation of statement . For example, statement is true for , , , , and other elements that are not transition elements.
