Types of Bonding and Lewis Structures

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

Example of Metallic Bonding

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

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

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

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

What type of bond exists between chlorine (EN = 3 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

What type of bond exists between nitrogen (EN = 3 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

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

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

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

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

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