<h2>Answer:</h2>
There is only one valence electron in Al(OH)4- anion.
<h3>Explanation:</h3>
- Valency is the number of electrons in the outer most shell of an atom.
- In this compound, aluminium has the valency of +3. It means Al needs only 3 electrons to complete its outer most shell.
- Hence the stable molecule Al(OH)3.
- But the addition of one another OH- leads to the negative charge and there is one spare electron which can make bond to an atom to stable the compound.
