Start studying Ion charges for selected elements. Learn vocabulary terms and more with flashcards games and other study tools. In what region of the periodic table are these multiple ion elements usually located.

These are called multivalent ions. NaCl Sodium chlorideCaSCalcium sulfideAg2SSilver sulfideZn3P2 Zinc phosphideAl2O3 Aluminum oxide SrCl3 Strontium chlorideModel 2 Ionic Compound Names Metals that form one ion. This is a chart of the most common charges for atoms of the chemical elements.

You can use this chart to predict whether or not an atom can bond with another atomThe charge on an atom is related to its valence electrons or oxidation stateAn atom of an element is most stable when its outer electron shell is completely filled or half-filled. To find the ionic charge of an element youll need to consult your Periodic Table. On the Periodic Table metals found on the left of the table will be positive.

Non-metals found on the right will be negative. But you need to know the specific ionic charge elments. The image below shows the general trend for ionic charge.

Model 1 Ion Charges for Selected Elements HI Transition elements Li Be2 N 3 2. Model 1 ion charges for selected elements hi. School Deer Park High School Deer Park.

Course Title SCIENCE chemistry. Pages 125 This preview shows page 99 - 102 out of 125 pages. Model 1 Ion Charges for Selected Elements H 1 Li 2 Be N3 O2 Na Mg 3 Transition elements CH p3- AlB S2 Fe2 Fe Ni2 Nis Cu Cu Ca 4 K Br Zn2 Rb Sn2 5 Sr Ag.

I- Sn4 Hg2 Hg 6 Ba2 Pb2 Pb4 Cations Anions Examine the table of ionic charges above in order to answer the following questions. For example the maximum charge of an aluminium cation third main group would be 3 the maximum charge of a sulfur anion sixth main group would be -2. Some elements form multiple ions but no charge will be larger than determined by the above method.

Is there a similar method or pattern to determine maximum charges of transition metals. Model 1 - 2 3 4 5 Ion Charges for Selected Elements 02 Cll- Bri- Be2 Mg2 Transi tion elements Cu2 Ca2 Sr2 Ba2 Sn2 Sn4 Pb2. Keep in mind that the sum of the charges in an ionic compound must equal zero.

Model 2 - Ionic Compound Names Metals that form one ion NaCl Sodium chloride Cas Calcium sulfide Ag2S Silver sulfide Zn P Zinc phosphide Al O Aluminum oxide SrCl Strontium chloride 4. Circle he symbol for the metal in each of the compounds in Model 2. The molecular structure has been optimized at the B3LYP6-31g level of theory.

Charges used for electrostatic maps are computed using the NBO method. The molecular vibrations are. The charge on each ion is NOT shown in the complete formula.

Thus the formula for a compound made from potassium ions K and sulfide ions S will be written as KS and indicates that 2 potassium ions are paired with one sulfide ion 2. Consider the ions of lithum Li and sulfur S. Write a chemical formula for the ionic compound formed from those ions using the simplest ratio of Li to S.

Remember the sum of the charges in an ionic compound must equal zero 3. Model 2 Ionic Compound Names Metals that form one ion N Cl Sodium chloride S Calcium sulfide S Silver sulfide Zn P Zinc phosphide Aluminum oxide Sr I Strontium chloride 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 2the metal. Model 2 Ion Charges for Selected Elements Key Questions 10. Draw a star-step line in Model 2 to separate the metals and nonmetals.

Consult a Periodic Table 11. Consider the ions listed in Model 2. In general do metals form anions or cations.

Propose a mathematical equation to calculate the charge on an ion from the number of protons and electrons in an ion. Confirm that your equation works using two positive ion examples and two negative ion examples from Model 1. Model 2 is labeled Metals that form one ion What other metals that form only one ion could be included in the Model 2 list.

Model 1 may be helpful in this regard. Describe how the names of the nonmetal elements in Model 2 are changed when they are in their anion forms. Name the following ionic compounds using what you learned from Model 2.
