First, draw an AlCl3 molecule, in dot-structure. You will see that in the molecule, Aluminum has only 6 electrons, 3 of which are shared with the chlorine atoms. It needs 2 more electrons to become more stable (8 electrons in the outer shell is usually stable). Now look at the chlorine atom in the AlCl3 molecule.It has 8 electrons, and thus, it is somewhat "stable". If a Chlorine atom from ANOTHER AlCl3 molecule formed a dative bond with the Aluminum atom(a dative bond is a covalent bond where both shared electrons come from just one species. In this case, both electrons come from the chlorine atom), this Al atom would now have 8 electrons as well. That is why AlCl3 exists as a dimer- as Al2Cl6 . It's structure is shown in this picture.

What does molecule of an element mean?
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
Why does AlCl3 exist as Al2Cl6 molecules?
Because the electronegativity difference between aluminum and chlorine is not very high, despite the fact that Al is a metal and Cl is a non-metal. This means the compound will have high covalent character, and will do certain things chemically that molecular compounds do, like form molecules, and bond in an amount that isn't lowest possible terms.
Is it true that an oxygen molecule has two atoms?
Yes, the diatomical molecule does exist as two oxygen atoms.
How does oxygen form a diatomic molecule?
Bcoz the qunatity of Oxygen present in the air is very high as it can't exist as a single molecule it always found in the form of Diatomic molecule that is O2
What is water made up of tms or molecules?
The molecule of water is H2O; the molecule contain atoms. Liquid water exist as molecules association.
Does CuCl2 exist as a molecule?
no
Is Na exist as a polyatomic molecule?
No.
Does NO2 exist as a molecule?
Yes
What molecule exist independently?
element
Does beryllium exist as molecule?
It is only an atom.
What is the smallest piece of sugar that can exist?
molecule
Which molecule is more likely to exist in nature a molecule of CH3 or a molecule of CH4 Explain?
The molecule of methane is more stable, carbon is tetravalent.
Why does hydrogen molecule does not exist?
Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.

Why a certain atom exist alone?
it can exist alone as a diatomic molecule eg O2 oxygen
What has 3 atoms in each molecule?
Molecule of nitrogen has 3 atoms of nitrogen. Nitrogen molecule exist as N3.
