The aluminum ion is Al3+ and the sulfide ion is S2-. The formula for aluminum sulfide is Al2S3. In an ionic compound, the size of the charge of each ion becomes the subscript on the opposite ion. This is called the crisscross rule. https://www.YouTube.com/watch?v=99NVKAss5LE&t=240s
Be+2 Cl-1 ------> these are the ions and their charges
Be+2 Cl-1 Cl-1 -------> make the charges add up to zero by adding a negative Cl atom to cancel out the +2 positive Be atom
BeCl2 ------> simplify
Name is Beryllium chloride
Al3+ and 3 Cl- form AlCl3
This chemical is a great catalyst for organic chemists- in Friedel-Krafts and chlorination of benzene.

Al is trivalent while Cl is monovalent so formula is AlCl3
Barium chloride is the compound which is highly soluble in water.
BeCl2 = Beryllium chloride
Aluminium sulfide is Al2S3.
BeBr2
hydrochloric acid HCl
H-F
HCl has an ionic bond.
HCl gas is a covalent molecular compound, HCl in water dissociates to form H+(aq) + Cl-
I'm assuming you mean hydrochloric acid, HCl? This would be a covalent molecule, because of both atoms being nonmetals.
H+, Cl-
hydrochloric acid HCl
Silane has the chemical formula SiH4; but silane has covalent bonds.
H-F
HCl has an ionic bond.
Examples are: Na+, Cl-, H+, OH-, [H3O]+.
HCl gas is a covalent molecular compound, HCl in water dissociates to form H+(aq) + Cl-
(H)++(Cl)- = (HCl)
I'm assuming you mean hydrochloric acid, HCl? This would be a covalent molecule, because of both atoms being nonmetals.
An example of covalent bond is ;H + H=H2 as covalent means sharing of electrons molecules is involved in covalent bond not ions. an example of ionic bond is; H+ + Cl-=H+Cl-
This is a covalent compound.
