SCH 3U- R.H.KING ACADEMY Name:________________________ Chemical Nomenclature Unit Valence Value The valence value of an element is defined as the number of electrons an atom of that element will gain/lose/share when forming a compound. Elements have a valence value determined by their group on the Periodic table unless otherwise indicated by the name. I 2 3 4 3 2 1 0 Cross-Over Rule for Writing Formulas STEPS 1. Write down the symbols of the elements in the order given in the name. 2. Write the valences above the elements symbol. 3. Divide the valences by the highest common multiple. 4. Cross-over valences 5. Drop all 1’s and unnecessary brackets sodium chloride magnesium oxide calcium fluoride lithium sulphate aluminum carbonate Na Cl Mg O Ca F Li SO4 Al CO3 1 1 Na Cl 1 1 Na Cl Na1Cl1 NaCl 2 2 Mg O 1 1 Mg O Mg1O1 MgO 2 1 Ca F 2 1 Ca F Ca1F2 CaF2 1 2 Li SO4 1 2 Li SO4 Li2(SO4)1 Li2SO4 3 2 Al CO3 3 2 Al CO3 Al2(CO3)3 Al2(CO3)3 Notes: a) You should be able to do all 5 steps in your head when you are finished the unit. b) When naming compounds, the least electronegative element is usually written first. c) Groups of elements such as SO42- and CO32- are referred to as radicals or polyatomic ions. These radicals behave as if they were a single entity and follow the cross over rule in the same manner as other single elements. Brackets are used in the formula only if there are 2 or more of the radical indicated in the formula. For example, brackets are used in Al2(SO4)3 but not Na2SO4. Binary Ionic Compounds A binary compound contains 2 elements only. Rules for Binary Ionic Compounds: a) The name of the binary compound always ends in "ide". b) The first mentioned element may have more than one valence and if it does this must be indicated in the name. c) If the valence of the first element is not indicated in the name, their valence value is determined by their group on the Periodic table. A) Binary Compounds where the first element has 1 valence only Use rule “c” and the cross-over rule. Silver has a valence of 1, zinc and cadmium have a valence of 2.

Due to this it is necessary to indicate the valence of the metal in the name of the compound using either the Stock (IUPAC or Roman Numeral) or Classical (“ous” and “ic”) method. The second element (non-metal) always has a valence equal to the value as determined from its group in the periodic table. The table of multivalent elements that you have been given must be MEMORIZED! Method 1: Stock/IUPAC/Roman Numeral Method This is the currently preferred method as the valence of the first is indicated using the corresponding Roman Numeral in brackets following the name of the first element.

Binary Acids This is a very small but common group of acids. The following rules apply to all of the members. 1. All have the prefix “hydro” and end with “ic”. 2. All must contain hydrogen as the first element. 3. Use the normal cross-over-rule to determine the formula. 4. All are made by dissolving the gas in water and must be so indicated by using (aq) behind the formula. 5. Have no oxygen in their formula Examples: hydrochloric acid HCl(aq) hydrosulfuric acid H2S(aq) hydrocyanic acid HCN(aq) Exercise: For all exercises give the name if the formula is provided and the formula if the name is provided. hydrobromic acid __HBr(aq)__ hydrotelluric acid ___H2Te(aq)_ hydrofluoric acid ___ HF(aq)__ hydroiodic acid __ HI(aq)___ hydroselenic acid ___ H2Se(aq)_ hydrosulfuric acid ___ H2S(aq)__ W7 SCH 3U- R.H.KING ACADEMY Name:________________________ 2. Oxy Acids This is a larger group of acids. They are alike in that they all contain H, O and at least one other non-metal element. All members of this group of acids follow the rules below. 1. 2. 3. 4. The name of the acid ends in “ic”. The name of the associated radical ends in “ate”. The valence value of the associated radical is equal to the number of acidic hydrogens in the acid. Since these acids are made by reacting a non-metal oxide with water, (aq) is not required but may be used. The following 6 oxy acids and their associated radicals along with their valences must be memorized.

Elements of the same chemical family (group) follow the pattern of the memorized oxy acid immediately above the element of interest. Example: memorized acid: fluoric acid = HFO3 therefore: chloric acid = HClO3 iodic acid = HIO3 bromic acid = HBrO3 If hydrogen is joined with the radicals learned earlier a few more acids can be formed. chromate = CrO42- chromic acid = H2CrO4 cyanate = CNO- cyanic acid = HCNO W8 SCH 3U- R.H.KING ACADEMY Name:________________________ Exercise: Complete the following chart for the acids listed.

Derived Oxy Acids Theses acids are all derived from the parent oxy acids which you are to memorize. The table below shows the rule to determine the derived oxy acids from the parent acid. When adding or removing oxygen atoms from the parent acid, the number of hydrogens on the acid and the valence of the associated radical remain the same as the parent.

According to this definition then, most of the compounds dealt with in the section on binary compounds could be considered to be salts formed from a base and a binary acid. In the same manner, salts are formed from a base and an oxy acid or derived oxy acid.
