MCQ
All the alkali metals have electronic configuration, $ns^1$ outside the noble gas core. They readily lose electron to give:
- ✓Monovalent ions.
- BDivalent ions.
- CTrivalent ions.
- DBoth $(a)$ and $(b)$.
✓
Answer
Correct option: A.
Monovalent ions.
Alkali metals have one valence electron $ns^1$ outside the noble gas core. So, they readily lose this electron to produce monovalent cation.
