Question
Why does an element have to lose or gain electrons?
- To lose more electrons
- To attain stability
- To attain inert gas configuration
- Both B and C
Hint:
To attain stability and to get an inert gas configuration, the atoms gain or lose electrons.
The correct answer is: Both B and C
- The atoms need to be stable to attain an inert gas configuration.
- If an atom has unpaired electrons in the valence shell, it will be unstable and tend to gain or lose an electron to make it stable.
- Thus the atoms gain or lose electrons to attain stability and inert gas configuration.
