Objectives To describe the formation of ions from their parent atoms To learn to name ions To predict which ion a given element forms by using the periodic table To describe how ions combine to form neutral compounds +/- e-

A. Ions In a chemical reaction atoms can form ions by gaining or losing electrons. Metals tend to lose one or more electrons to form positive ions called cations. Cations are generally named by using the name of the parent atom.

A. Ions Nonmetals tend to gain one or more electrons to form negative ions called anions. Anions are named by using the root of the atom name followed by the suffix –ide.

A. Ions Ion Charges and the Periodic Table The ion that a particular atom will form can be predicted from the periodic table. Elements in Group 1 and 2 form 1+ and 2+ ions, respectively Group 7 atoms form anions with 1- charges Group 6 atoms form anions with 2- charges Elements close to the sides of the Periodic Table gain or lose electrons to reach a “noble gas configuration”

A. Ions Ion Charges and the Periodic Table

Ions What ions would be formed from the elements with the following atomic numbers? Also what noble gas has the same number of electrons as these ions? 53 38 7 55 88 9 13

B. Compounds That Contain Ions Ions combine to form ionic compounds. Properties of ionic compounds High melting points Conduct electricity If melted If dissolved in water

B. Compounds That Contain Ions Ionic compounds are electrically neutral. The pluses are balanced by the minuses The charges on all the anions and cations in the compound must sum to zero / be in balance. Remember This

B. Compounds That Contain Ions Formulas for Ionic compounds Write the cation element symbol followed by the anion element symbol. The number of cations and anions must be correct for their charges to sum to zero.

Ionic Compounds What compound would be formed by the following ions? Na+ and Cl- K+ and F- Fe3+ and P3- Na+ and S2- Mg2+ and Cl- Mg2+ and O2- Fe3+ and Cl- Na+ and P3- Fe3+ and S2- Mg2+ and N3- What would be the symbol of an ion of the isotope Nitrogen 15?
