Question
- A. Unreactive gases with full outer electron shells
- B. Reactive metals that form +1 ions
- C. Diatomic halogens that form -1 ions
- D. Transition metals that form coloured compounds
Answer
Unreactive gases with full outer electron shells
Explanation
The correct option is "Unreactive gases with full outer electron shells". Group 0 elements are noble gases with full outer electron shells, so they are very unreactive. The other choices describe Group 1, Group 7, or transition-metal behaviour instead.
Common mistake
Misidentifying Noble Gases
Students often confuse noble gases with other groups, thinking they are reactive like alkali metals.
Remember that noble gases are in Group 0 and are characterized by their stable electron arrangements, making them unreactive.
