To put it simple, in general:
an acid donates a proton/positive charge; this means it steals an electron/negative charge. This is how acids form bonds with other compounds
Since the aluminum in aluminum chloride forms 3 bonds with the chlorides, it is obviously missing a pair of electrons (or bond).
So, in a reaction, the aluminum in this compound tends to steal a pair of electrons from another compound. This "stealing of a pair of electrons" makes the fourth bond with the other compound. Now all the atoms have octets (8 valence electrons) and they're all happy :)
PS: A bronsted acid donates a proton (hydrogen atom), and a Lewis acid steals a pair of electrons to make a bond
aluminum trichloride
aluminum has a +3 oxidation state and is very electron deficent. in this state it is more electronegative and the polarity is small enough to be considered convalent
in fact the +3 aluminum is a good Lewis acid
It isn't because a covelant bond is a bond between 2 nonmetals and aluminum is a metal and chlorine is a nonmetal
It is neither a bronsted acid or a Lewis acid.
A covalent bond is between two non-metals. An ionic bond is between a metal and a non-metal. Since aluminum is a metal and chlorine is a non-metal, they are ionically bonded.
Fluorine by itself is an element. An ionic bond is formed between the attraction of two ions with opposite charges (positive/negative). For Example- NaCl sodium chloride(table salt) Sodium is positively charged and Chlorine is negatively charged. In Covalent bonds, the compound is made by two atoms sharing their valance electrons, or the electrons in the outermost ring, For example H2O(water). There are Two Hydrogen atoms (Hydrogen is in the first group therefor has 1 valance electron) plus one Oxegyn Atom (Oxegyn is found in group eight therfor has 6 valance electrons) They want to have a full outer ring (eight electrons) so this compound works.

Only non-metal+non-metal is considered covalent. Plus, protons are NEVER shared; just the electrons.
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
copper chloride
A compound of aluminum and chlorine has an ionic bond.
covalent bond
2 AlBr3 + 3Cl2 -> 2AlCl3 + 3Br2
Here is a covalent bond.
It's a covalent bond.
This chemical reaction is:2 AlBr3 + 3 Cl2 = 2 AlCl3 + 3 Br2
Covalent bond between Si and S.
The bond in the ammonium ion (NH4+) is a covalent bond. The nitrogen atom forms covalent bonds with each of the four hydrogen atoms by sharing electrons.
covalent bond
Yes they would!
it is a polar covalent bond. Scince oxygen does not follow the octet rule(only 8 electrons, needs ten) and hydrogen has one electron, two hydrogen electrons plus eight oxygen electrons equal ten :)
It is ionic, because any bond between a hydrogen atom and a polyatomic ion (Hydrogen + polyatomic ion = acid) is always ionic. H+ plus Cl-: hydrogen is a positive ion, chlorine is a negative ion, they attract, HCl is formed, which is hydrochloric acid.
