Calcium has a +2 oxidation number and chlorine has a -1 oxidation number. The Ca+2 and the Cl-1 will hook up in a one-to-two ratio, and you'll see CaCl2 as the molecular formula for calcium chloride.
AlF3. Aluminum trifluoride.
The ionic compound expected to form between fluorine (F) and calcium (Ca) is calcium fluoride, with the chemical formula CaF2. In this compound, calcium donates two electrons to each fluorine atom, resulting in the formation of Ca2+ and F- ions that combine in a 1:2 ratio to achieve a neutral overall charge.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
The ionic compound formed between Cl and Ba is expected to have the formula BaCl2. This is because barium typically forms ions with a 2+ charge (Ba2+), while chlorine typically forms ions with a 1- charge (Cl-). To balance the charges and achieve neutrality in the compound, two chlorine ions are needed for every barium ion.
The expected formula between calcium and oxygen is CaO, which is calcium oxide. This compound is formed by the combination of one calcium atom with one oxygen atom.
Ca2+ + 2 I- --> CaI2
AlF3. Aluminum trifluoride.
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!)

Al3+ and 3 Cl- form AlCl3This chemical is a great catalyst for organic chemists- in Friedel-Krafts and chlorination of benzene.
Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
The chemical name refers to the full name of a compound, while the chemical formula represents the composition of elements in that compound using symbols and subscripts. The chemical formula provides information about the elements and their ratios in the compound, while the chemical name typically includes the names of the elements and possibly other descriptive terms.
