Aluminium is formed at the cathode because the Al ions (Al3+) within the electrolyte are attracted to form aluminium metal by gaining 3 electrons.
The metal is molten due to the high temperature of the cells.
Hope this helps

∙ 14y agometals lose electrons and become positively charged.. and are attracted to the negative electrode (cathode) this is why metals deposit at the cathode.

∙ 12y agoAluminium ions have a 3+ charge so are therefore attracted to the cathode, which has a negative charge.

∙ 11y agoAs Aluminium becomes as positive ion by losing three electrons.

Why alumina is electrolysed in molten state?
In solid state, Aluminium and oxide ions are immobile. When aluminum oxide is melt down,aluminum and oxide ions become free and they can easily migrate to respecve electrodes. Therefore, aluminum oxide is electrolysed in molten state.
What are the ions present in limewater?
The ions corresponding to the electrolyte i.e. both anions and cations are present in an electrolyte. These ions may be similar to the electrodes dipped in it.
Do positive ions form faster than negative ions?
yes positive ions are faster then negative ions
Is an ion negative or positive?
Ions can be either positive or negative P.S. but negative ions are way better for you
Where do the negative ions go?
Negative ions go to a positive electrode.
An electrolytic cell is made with zinc and aluminum electrodes Which of the following happen at the cathode of this cell?
Aluminum is reduced. Zinc ions are formed.
What does electrolysis use to separate molecules in a chemical change?
The electrolysis ionize the particles/ molecules present in the particles and charged the positive and negative ions. Positive ions collected on negative electrode and Negative ions collected on positive electrodes.

What is a battery end called?
Electrodes... Positive (anode) and Negative (cathode) electrodes which are attached to the terminals. The electrodes provide the chemical energy which is converted to a flow of electrons. And the electrolyte, the electrolyte separates the electrodes but allows for the passages of electrons and ions for the electro-chemical reaction of the electrodes.
Which would form a negative ion lithium aluminum magnesium or chlorine?
Chlorine would form a negative ion and the other three positive ions.
Which species has a negative charge?
An electron or an aluminum ion carry a negative charge.
Why are acidic liquids good conductors?
Acidic liquids are good conductors due to the high concentration of hydrogen ions (H+) which can move around the liquid, carrying the electric current between the positive and negative electrodes. Acids have a low pH value and a high concentration of H+ ions.
How does an electrolytic cell work?
A voltage applied across two electrodes causes electrons to flow
How many ions are in sulfate in Al2SO4?
There are 3 ions in the formula Al2SO4 (2 aluminum and 1 sulfate), but this formula is wrong. The formula of aluminum sulfate is Al2(SO4)3 which contains 5 ions: 2 aluminum ions and 3 sulfate ions.
How are aluminum ions joined together to form a can?
electrons are shared between all aluminum ions in the bar
Which ion is attracted to which electrode?
because chloride ions being negatively charged have got a tendency to get attracted to positive ions( follows from coloumbs law) and since positive electrode contains positive ions so chloride free ions in solution gets attracted to the positive electrode....
