  1. LECTURE 2.1 – IONIC BONDING

  2. Today’s Learning Target • LT 2.3 – I can hypothesize the compound that forms between two ions. Furthermore, I can discuss the role that electronegativity and ionization energy played in the formation of this ionic bond. • LT 2.4 – I can explain how electrostatic attractions lead to the formation of visible salt crystals. In this explanation, I can incorporate the idea of electrostatic attraction, positive charge, and negative charge.

  3. How are bonds formed?

  4. I. Electrons and Bond Formation • Bonds form due to the movement of electrons • Electrons can be either shared or transferred between elements • Exchange occurs so elements can gain a full Octet.

  5. How do ionic bonds form?

  6. Chemical Bonding Ionic Bonds Metallic Bonds CovalentBonds

  7. I. Ionic Bonds • Ionic Bond– A bond that forms between ions as a result of the elements exchanging electrons. • Formed between metals and non-metals • Bond forms due to cation – anion attraction that results from transferring electrons

  8. Ionic Bond Formation

  9. II. Ionization Energy, Electronegativity and Ionic Bond Formation • Ionic bonds form because an atom with a low ionization energy loses its electron an element with a high IE.

  10. Ionic Bond Formation

  11. How do monoatomic bonds form?

  12. I. Element Vocabulary Al3+3 Subscript – The number in the lower right corner. Superscript– The number in the upper right corner.

  13. II. Monoatomic Ionic Bonds • An ionic bond that forms between 2 elements is known as a monoatomic ionic bond. • When elements bond, they form a compoundthat has new properties. • New compounds do not have a charge.

  14. Class Example • What is the compound that forms between calcium and fluorine?

  15. Table Talk • What is the compound that is formed between magnesium and phosphorus?

  16. Stop and Jot • What is the compound that is formed between sodium and nitrogen?

  17. How do polyatomic bonds form?

  18. Stuck Together

  19. I. Polyatomic Ionic Bonds • Sometimes, there are charged compounds of two non-metals. • Known as polyatomic ions • These ions can form ionic bonds with other elements

  20. Class Example • What is the compound that would form between aluminum and SiO32-

  21. Table Talk • Determine the ionic compound that forms between barium and OH-

  22. Stop and Jot • Determine the ionic compound formed between cesium and CO32-.
