  6. Classification of Matter

  7. Formation of Ionic Bonds • Opposites _____________________. • A metal loses an electron(s), and the nonmetal gains an electron(s). • Cation and anions form as a result. • The two ions are electrostatically-attracted, and form an ionic bond.

  8. Ionic Bond • Ionic bond: the electrostatic force that holds oppositely charged particles together in an ionic compound • Compounds that contain ionic bonds are called ionic compounds. • Ionic compounds form between metals and nonmetals.

  35. Physical Properties of Ionic Compounds WHY? Applying heat to melt sodium chloride Applying a current to test conductivity of sodium chloride

  36. Forming Ionic Compounds Pre-Lab • Lab Purpose: To write formulas and names of 20 ionic compounds; to see ionic compounds formed in the lab • Lab Safety: Wear goggles and apron. Avoid contact with chemicals. Wash your hands after the lab. Do not mix up the pipettes. • Lab Procedure: Note the layout of the test tubes. Place 4-5 drops of each chemical into the well-plate. • Lab Report: Turn in your data table at the conclusion of the lab. We’ll pass them up when we return to our seats. • Post-Lab Clean-up: Place your well-plate on the table beneath the goggle cabinet. Wipe down your station.

  37. Ionic Exit • Throughout this unit, there will be several quizzes on ionic and covalent compounds. • Correctly name or write the formula for as many of the following ionic compounds as you can to receive up to 5 extra credit points in this Unit

  38. Indium Permanganate

  39. ZnCl2

  40. Palladium (III) Hydrogen Phosphate

  41. MnI4

  42. Lithium Chlorite

  43. SrCr2O7

  44. As you come in, • The Material: • Paper and pencil for notes • Remote control • Paper, periodic table, and pencil for quiz • The Plan: • Take the Ionic Compound Quiz • Learn about COVALENT COMPOUNDS • The Assessment: • Covalent & Acid Quiz – Thursday • Combined Ionic, Covalent & Acid Quiz - Friday

  45. Starter • Which of the following formulas is incorrect? Name the correct ionic compounds. RaCl2 Ag(HSO3)2 Al(PO4)4 • When a CATION forms…which of the following actually happens? • The # of protons changes • The atom gets lighter or weighs less • The atom loses electrons

  46. Covalent Bonding

  47. Why do atoms bond? • Remember that ionic compounds form by gaining and losing electrons. • Covalent compounds form when 2 atoms both need electrons. • They can both achieve the full octet by SHARING electrons.

  48. What is a covalent bond? • Covalent bond: chemical bond that results from sharing electrons • Covalent bonding generally occurs when elements are relatively close together on the periodic table. • The majority of covalent bonds form between nonmetallic elements…often groups 4A to 7A.

  49. Naming Covalent Compounds • First, you must be sure that the compound is COVALENT by analyzing the formula. • Second, you use prefixes to communicate the number of atoms of each element that form the compound. • Example: H2O = dihydrogen monoxide

  50. Prefixes • Six = hexa • Seven = hepta • Eight = octa • Nine = nona • Ten = deca • One = mono • Two = di • Three = tri • Four = tetra • Five = penta NEVER USE MONO ON THE FIRST ELEMENT NAME. ALWAYS USE THE -IDE ENDING ON THE SECOND ELEMENT NAME.
