Among the alkali metals caesium is the most reactive because
- A its incomplete shell is nearest to the nucleus
- B it has a single electron in the valence shell
- C it is the heaviest alkali metal
- D the outermost electron is more loosely bound than the outermost electron of the other alkali metals.
Answer & Solution
Correct Answer
(D) the outermost electron is more loosely bound than the outermost electron of the other alkali metals.
Step-by-step Solution
Detailed explanation
Among the alkali metals, caesium is most reactive because the outermost electron is more loosely bound than the outermost electron of other alkali metals.
