Firstly, Al has three valence elctrons , iodine has seven. Al will form 3 covalent bonds to iodine atoms giving it 3 shared electron pairs, giving the compound AlI3. However aluminium does not have full octet, wheras iodine does. A coordinate dative bond from an iodine on one AlI3 unit to another AlI3 would give the aluminium a full octet. this is what happens the molecular formula for AlI3 is Al2I6. a bridged dimer. ( You can't logically discount any (AlI3)n structure you could draw infinite chains or cyclic structures as well as dimers.)

Use Lewis theory to determine the formula for the compound that forms from Sr and Se?
SrSe
What is the chemical formula of the compound made by combining calcium and oxygen Use Lewis structures to help you decide your answer.?
The calcium oxide is CaO.
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
How did Gilbert Lewis change the definition of an acid?
He modified the definition of acids to include Lewis acids. A Lewis acid is a species that can accept a lone pair of electrons from another species. Conversely, a Lewis base is a species that can donate a lone pair of electrons to another species. Previous definitions of acids and bases include the Bronsted-Lowry theory, which says that an acid is a compound that produces H+ ions and a base is a compound that produces OH- ions.
Which of an atom's electrons are represented as dots in a Lewis structure?
Lewis dot formula
Use Lewis theory to determine the formula for the compound that forms from Sr and Se?
SrSe
How can Lewis theory be used to determine the formula or ionic compounds?
"To use Lewis theory to determine the formula of an ionic compound, determine the number of valence electrons lost by the metal to form an octet, and the number of electrons gained by the nonmetal to form an octet." Refer the link below for further reading.
Lewis theory predicts that the formula for a compound between fluorine and calcium is?
CaF2
What is the Lewis theory formula for the compound that forms between Li and N?
LiN
Which scientist described a base as a compound that donates an electron pair?
Its the Lewis Theory He also made the theory about the electron dot structures
What is the formula for the compound boron chloride?
BCl3 is the formula for Boron Chloride. As a matter of interest it does not obey the octet rule. It is also called a Lewis Acid.
What is the chemical formula of the compound made by combining calcium and oxygen Use Lewis structures to help you decide your answer?
CaO
Scientists described a base as a compound that donates an electron pair?
The Lewis Theory describes a base as a compound that donates an electron pair. By donating the electron pair there is a covalent bond.
