  1. CHEMICAL BONDS - Ionic Chapter 6

  2. 6.1 BONDING - journal • Begin filling in the table on the top of the Bonding Basics – Ionic Bonding Worksheet.

  3. 6.1 BONDING • Chemical PROPERTIES depend on the number of valence electrons.

  4. 6.1 BONDING • Therefore, chemical bonding and reactivity depend on an element’s electron configuration.

  5. 6.1 BONDING • STABLE ELECTRON CONFIGURATION: • Which group does this describe?

  6. 6.1 BONDING • What do elements with UNSTABLE ELECTRON CONFIGURATIONS do?

  7. 6.1 BONDING • They BOND and form compounds • IONIC BONDING

  8. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer • Both Sodium and Chlorine are now STABLE in their highest energy levels

  9. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer • What types of elements are Sodium and Chlorine?

  10. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal.

  11. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal. • When an atom gains or loses electrons, what does it get? • A CHARGE.

  12. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal • ION: An atom with a positive or negative CHARGE from electron transfer.

  13. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal • In the bond, one becomes positive (loses electrons) and one becomes negative (gains electrons).

  14. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal • Positive Ion (loses electrons): Cation • Negative Ion (gains electrons): Anion

  15. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal • WHAT DO OPPOSITE CHARGES DO?

  16. 6.1 BONDING • IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal • ATTRACT. • This is when the IONIC BOND forms.

  17. 6.1 BONDING • HOW can you predict which elements will make positive cations and which will make negative anions?

  18. 6.1 IONIC BONDING • Ionization Energy: the ability to PULL ON ELECTRONS. • Which side has the MOST PULL? • Which side GIVES UP electrons more easily? Look at “Data Analysis” at the top of page 160.

  19. 6.1 IONIC BONDING • Ionization Energy: the ability to PULL ON ELECTRONS. • Take out your Periodic Table. • Predict the OXIDATION NUMBERS (charges) of the ions for A Groups

  20. 6.1 IONIC BONDING • PROPERTIES OF IONIC COMPOUNDS • Form between a metal and a nonmetal • Brittle/crystalline • High melting/boiling points • Dissolve (ions come apart) in water & conduct electricity

  21. 6.1 IONIC BONDING • NAMING IONIC COMPOUNDS • NaCl – Sodium Chloride • HF – Hydrogen Fluoride • MgI2 – Magnesium Iodide • KBr - ??? Potassium Bromide This is Binary Nomenclature Ionic Bonding Challenge

  22. IONIC BONDING • POLYATOMIC IONS Sometimes groups of atoms can have a positive or negative charge. COMMON POLYATOMIC IONS • NH4+ – Ammonium • NO3- – Nitrate • OH1- - Hydroxide • CO32- – Carbonate • SO42- - Sulfate • PO42- - Phosphate

  23. 6.1 IONIC BONDING • NAMING COMPOUNDS WITH POLYATOMIC IONS • CaCO3 • Calcium carbonate • HNO3 • Hydrogen nitrate (nitric acid) • NH4Cl • Ammonium chloride • NaOH • Sodium hydroxide

  24. 6.1 IONIC BONDING

  25. 6.1 IONIC BONDING – Journal 2 • Ionization Energy: the ability to PULL ON ELECTRONS. • FOLLOW THE DIRECTIONS AT THE TOP OF THE BLANK PERIODIC TABLE FROM THE BACK OF THE ROOM.

  26. 6.1 BONDING – Journal 2 • Define ionic bond • Define ionization energy • Take out your Ionic Bonding basics worksheet and make sure you have a Lewis Dot for each element on the page, front and back • Begin filling out the Covalent Bonding Basics Table
