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
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.

because the hydrogen ion (H+) donates both electrons to the oxygen atom in water (H2O) to form the hydronium ion (H3O+), resulting in a shared pair of electrons from just one atom. This type of bond is called a coordinate covalent bond because both electrons in the shared pair come from one atom.
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
B. Electrons are shared. Covalent bonds involve the sharing of electrons between atoms.

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.
A covalent bond is formed between hydrogen and nitrogen.
The bond in the ion is covalent; but ammonium salts are ionic compounds.
No, H3O+ is not a coordinate covalent bond. It is a hydronium cation formed by the combination of a water molecule and a proton, and it has a regular covalent bond between the oxygen and the hydrogen atoms.
Yes they would!
The balanced chemical equation for this reaction is: 2AlBr3 + 3Cl2 → 2AlCl3 + 3Br2.
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 :)
