How many valence electrons in Al(OH)4-

Chemistry

Amanda [17]3 years ago

Answer: There is 1 valence electron in Al(OH)4-

Explanation:

The valence electrons are the electrons that are present in the outer shell of an atom.

In this case, the "Al" works with 3 electrons of valence, while the "OH-" has only 1 electron of valence, however we have 4 atoms of "OH-", in this case, the OH- donates a lone pair of atoms to make the covalent bonds with the "Al"  but  kind of weak, that is why , usually this molecule has special conditions to be formed, like high pH, where the negative state remain longer.

<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.

Answer:

The word "Halloween" comes from All Hallows' Eve and means "hallowed evening."

Halloween's origins can be traced back to the ancient Celtic festival known as Samhain, which was held on November 1 in contemporary calendars. It was believed that on that day, the souls of the dead returned to their homes, so people dressed in costumes and lit bonfires to ward off spirits.
