Circle the symbol for the metal in each of the compounds in Model 2.
Which element comes first in the name and formula of the compounds in Model 2the metal. Ionic compounds are compounds made up of ions. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the resulting ions have achieved an octet.
Below is a chemistry quiz on ionic compounds names and formulas give it a shot and see if you understood all we covered in this topic on Ions. Write the chemical formula for hexaboron silicide. Oxygen Express your answer as an ion.

Use Lewis dot structures to show the covalent bonding in the following. In this exercise you will evaluate some representative models to develop the rules used to classify a compound to predict the formula of a compound and to name the compound. This exercise is just the beginning of the work needed to be done to master the rules of writing formulas and nomenclature.
Your textbook has tables of the names and formulas of common cations and anions and discusses. Aluminium aluminum in American and Canadian English is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals at approximately one third that of steel.
It has a great affinity towards oxygen and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver both in its color and. For an ionic compound composed by reacting the metal aluminum and the nonmetal bromine the aluminum ion has a 3 charge while the bromide ion has a 1- charge.
There needs to be 3 bromide ions so. Every compound has its own CHEMICAL FORMULA and its own NAME. The nomenclature naming systems for IONIC and MOLECULAR compounds are different.
These consist of any positive ion except H combined with any negative ion. If H is the positive ion the compound is an acid as we will see later on page 6 The positive ion cation may be a monatomic metal ion such as. The name of this ionic compound is aluminum fluoride.
The name of this ionic compound is potassium chloride. Exercise PageIndex3 Name each ionic compound. Ca 3 P 2.

If you are given a formula for an. If the formula is given write down the name and if the name is given write down the formula. Use these pages as a study guide.
As a general rule you should know the names and symbols for elements 1-36. In addition you should know names and symbols for all elements in Groups I and II as well as the halogens Group VII noble gases Group VIII and some other metals used frequently. Write the formula for each compound.
Systematic name Asked for. A Identify the cation and its charge using the location of the element in the periodic table and Table 22 Some Common Monatomic Ions and Their Names Table 23 The Physical Properties of Typical Ionic Compounds and Covalent. 25152-52-7 Al 2 O 3.

1302-82-5 Al 4 C 3. 1299-86-1 Al 6 O 13 Si 2. Simple Binary Ionic Compounds Please complete the following table.
Formula of Ionic Compound s 2. Name of Ionic Compound. The charge of the metal ion is determined from the formula of the compound and the charge of the anion.
For example consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2 or 3 see Molecular and Ionic Compounds and the two corresponding compound formulas are FeCl 2 and FeCl 3. The simplest name iron chloride will in this case be.
The formula is AlPO 4 and the name of the compound is aluminum phosphate. Neither charge is an exact multiple of the other so we have to go to the least common multiple of 6. To get 6 we need three ironII ions and to get 6 we need two phosphate ions.
The proper formula is Fe 3 PO 4 2 and the compounds name is ironII phosphate. N Zinc phosphide Al Aluminum oxide Strontium chloride Sr 4. Circle the symbol for the metal in each of the compounds in Model 2.
Which element comes first in the name and formula of the compounds in Model 2 or the nonmetal. The name or symbol of the metal comes first. Use the table of ions in Model 1 to answer the following questions.
In the compound zinc phosphide what is the. 4 copper I phosphide 5 tin IV selenide 6 gallium arsenide 7 lead IV sulfate 8 beryllium bicarbonate 9 manganese III sulfite 10 aluminum cyanide 11 CrPO 4 2 12 VCO 3 2 13 SnNO 2 2 14 Co 2 O 3 15 TiC 2 H 3 O 2 2 16 V 2 S 5 17 CrOH 3 18 LiI 19 Pb 3 N 2 20 AgBr Ionic Naming Practice Problems - Solutions 1 NaBr. Answer Key Ionic Molecular or an Acid Honors Chemistry Write which type of compound it is whether the compound is ionic molecular or an acid.
If there is a multi-valent metal present write both the stock and classical name. Formula Type Chemical Name CaO I Calcium oxide C 2 H 2 M Dicarbon dihydride LiOH I Lithium hydroxide SO 3 M Sulfur trioxide. 1 aluminum atom and 3 bromine atoms.
2 sodium atoms 1 sulfur atom and 4 oxygen atoms. 1 magnesium atom 2 nitrogen atoms and 4 oxygen atoms. Write a chemical formula for each molecular model.

Naming Ionic Compounds Practice Worksheet - Solutions Name the following ionic compounds.
1 NH4Cl ammonium chloride 2 FeNO33 iron III nitrate 3 TiBr3 titanium III bromide 4 Cu3P copper I phosphide 5 SnSe2 tin IV selenide 6 GaAs gallium arsenide. Write each chemical formula and name each compound correctly. The instructor should also review the score for forming each compound.
Scoring is described in step 5 of the procedure. This activity is a game but it is also meant to be a teaching tool for proper naming procedures. Students will hopefully learn by repeatedly practicing naming simple compounds.
Instructors should emphasize team. The subscripts in the formula must produce an electrically neutral formula unit. That is the total positive charge must equal the total nega tive charge 3.
The subscripts should be the smallest set of whole numbers possible. If there is only one of a polyatomic ion in the formula do not place parentheses around it. Eg NaNO 3 not NaNO 3.
If there is more than one of a polyatomic. Ca 3 P 2. IronII chloride or ferrous chloride The cation charge must be specified since iron can form more than one charge.
Ionic Compounds Containing a Metal and a Polyatomic Ion. Metals combine with polyatomic ions to give ionic compounds. Name the cation first specifying the charge if necessary then the polyatomic.
