The answer is: The name of the positively charged nonmetal ion is changed to end in –ide.

For example, a chemical compound containing sodium and chlorine is binary ionic compound sodium chloride (NaCl).

In this compound, sodium (Na) has positive charge and chlorine (Cl) has negative charge.

Chlorine is nonmetal and sodium is metal.

Metals have positive charge and nonmetals negative.

Answer:

Explanation:

So, the formula for the compound should be:

$XCl_{6}$

Now we assume that we have 1 mol of substance, so we can make calculations to know the molar mass of element X, as follows:

$M_{Cl}=35.45g/mol\\$

So we have that 6 moles weight 212.7g, and we can make a rule of three to know the weight of compound X:

$212.7g\rightarrow 86.9\%\\x\rightarrow 13.1\%\\\\x=\frac{212.7g*13.1}{86.9} =32.06g$

As we used 1 mol, we know that the molar mass is 32.06g/mol

So the element has a molar mass of 32.06 g/mol and an oxidation state of +6, with this information, we can assure that the element X is sulfur, so the compound is $SCl_{6}$
