1 Types of Bonding and Lewis Structures Quiz on Monday

2 Describe the structure of metallic bonding. Positive metallic ions surrounded by electrons.

3 Example of Metallic Bonding

4 What type of bonding must exist if a substance can conduct electricity dry? Why? Metallic; the delocalized electrons are able to flow freely around the positive metal ions

5 Potassium bromide forms a crystal lattice structure. What type of bonding would you expect it have? Ionic

6 If a substance dissolves in water and makes a solution that conducts electricity, what types of bonds do you expect hold it together? Ionic; forms ions in solution to make it an electrolyte

7 If a substance melts in your hands, what type of bonds do you expect to hold it together? Covalent (polar and non-polar); covalently bonded substances have low melting points

8 Which of these elements would make a covalent bond with nitrogen? AlMgBaC C; non-metal with non-metal bonding (also similar electronegativity)

9 Which of these elements would make an ionic bond with potassium? MgNSrCl N, Cl; metal with non-metal bond (also difference in electronegativities is relatively large)

10 Which of these elements would make an ionic bond with chlorine? OFLiXe Li; metal with non-metal bond (also difference in electronegativities is relatively large)

11 What type of bond exists between chlorine (EN = 3.0) and bromine (EN = 2.8) Non-polar covalent; both elements are non-metals with their difference in electronegativity being less than 0.5

12 What type of bond exists between nitrogen (EN = 3.0) and hydrogen (EN = 2.1) Polar covalent; both elements are non-metals with their difference in electronegativity being between 0.5 and 1.7

26 Which element has the following electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6 Iron, Fe

27 Which element has the following electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 3 Arsenic, As

28 Write the orbital notation for the element carbon ↑↓ ↑↓ ↑ ↑. 1s 2s 2p

29 Write the orbital notation for the element sulfur ↑↓ ↑↓ ↑↓ ↑↓ ↑↓. 1s 2s 2p ↑↓ ↑↓ ↑ ↑. 3s 3p

30 Write the orbital notation for the element selenium ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ 1s 2s 2p 3s3p4s 3d 4p

31 Write the Lewis Dot structure for the following atoms and their ions

32 Aluminum Al (group 13; 3 valence electrons) Al +3 (aluminum loses its 3 valence electrons to satisfy the octet rule)

33 Phosphorus P (group 15; 5 valence electrons) P -3 (phosphorus gains 3 electrons to satisfy the octet rule)

34 Helium He (group 18 but it has 2 valence electrons) No ionic form of helium. It already has a full valence shell so it already satisfies the octet rule

35 Strontium Sr (group 2; 2 valence electrons) Sr +2 (strontium loses its 2 valence electrons to satisfy the octet rule)
