Which formula represents a binary compound

If the metal has only one ion, then the Roman numeral is not necessary. Also, Greek prefixes are not used when naming ionic compounds. Binary Molecular Compounds When naming molecular, or covalent, compounds, if an element in the formula has a subscript, the name of that element includes a Greek prefix that means the subscript number.

The name of the second element is changed in the same way as ionic compounds. Greek prefixes are used on both elements, if required. If the first element in the compound has no subscript, no prefix is used. How do you write the name and formula of a binary compound? Chemistry Matter Compounds. Jan 13, See the explanation.

Formula: FeN. No, It shows the formulas of 2 compounds, neither of which are binary. Each of the compounds above has 3. There is no 'binary formula'. You can say that hydrogen iodide is a binary compound, that is one formed from just two elements.

HI is its formula. Zinc and chlorine react to form the binary ionic compound zinc chloride, which has the formula ZnCl2. No, in a binary compound the second element is given the prefix -ide.

The first step in writing formulas when given the systematic name of a binary covalent compound is to recognize the name as representing a binary covalent compound.

It will have one of the following general forms. Follow these steps for writing formulas for binary covalent compounds when you are given a systematic name. Notice that they are the reverse of the steps for writing names from chemical formulas.

Write subscripts indicated by the prefixes. If the first part of the name has no prefix, assume it is mono-. You will also be expected to write formulas for the compounds whose nonsystematic names are listed above. Binary Covalent Nomenclature Help.

Converting Formulas to Names Memorized Names Some binary covalent compounds, such as water, H 2 O, and ammonia, NH 3 , are known by common names that chemists have used for years. Follow these steps to write the names for binary covalent compounds. Add -ide to the end of the name. Exceptions Hydrogen atoms always form one covalent bond, and halogen atoms group 17 or 7A usually form one bond.
