Write subscripts for each formula so as to yield an uncharged compound. We begin with inorganic compounds and then turn to simple organic compounds that contain only carbon and hydrogen. You will also be expected to write formulas for the compounds whose nonsystematic names are listed above.
These two steps give the full name of H2S. You should avoid using this less accepted name, but because many people still use it, you should know it. If both elements are in the same group, the element closer to the bottom of the column is named first.
Write the formula, including the charge, for the anion. Students often confuse the two sets of rules. Since the positively-charged ion will be attracted to the negative electrode opposites attractthe ion attracted to the cathode is called the CATION.
The water, H2O, you boil to cook your potatoes and the methane, CH4, in natural gas that can be burned to heat the water are examples of binary covalent compounds.
Polyatomic ions can take the place of monatomic anions, so formulas that contain a symbol for a metallic element and the formula for a polyatomic ion represent ionic compounds.
The names of the anions are below. Na2S First symbol is Na, so the first part of the name is sodium.
Write the symbols for the elements in the order mentioned in the name. Ionic compounds whose formula contains one symbol for a metal and one symbol for a nonmetal are called binary ionic compounds.
Name the following binary ionic compounds: The reason for this is that we know that the less electronegative elements are to the left and bottom of the periodic table. For example, because nitrogen and oxygen are nonmetallic elements, the formula N2O3 represents a binary covalent compound.
Write the formula, including the charge, for the cation. There are only 5 elements which you need to memorize which have more than one oxidation number and they are: Binary Covalent naming Converting Names to Formulas 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.
Use root of its full name which is brom- plus the ending "-ide. There can also be several of each element such as Na2O or AlBr3.Title: Ionic Compounds: Naming Last modified by: TSS Document presentation format: On-screen Show Other titles: Times New Roman Arial StarSymbol Default Design Topic: Naming Ionic Compounds Do Now: Which element forms a compound with chlorine with the general formula MCl (where M is your unknown element) A.
