Bonds

Question 1

Ionic Bonds

Answer 1

the transfer of electrons between molecules of two different electronegativities
(metal with non metal)

Question 2

Covalent bonds

Answer 2

the sharing of electrons between two molecules with similar electronegativities
(two nonmetals)

Question 3

Ionic Properties

Answer 3

Properties: high melting point (MP), high boiling point (BP), brittle, hard.
Forces: ionic interactions (lattice structure)
Ex: NaCl MgO

Question 4

Molecular Properties

Answer 4

Properties: low MP, does NOT conduct electricity
Forces: intermolecular forces
Ex: H2O, Cl2, CH4

Question 5

Network Covalent Properties

Answer 5

Properties: high MP, high BP, hard, does NOT conduct electricity
Forces: network of covalent bonds
Ex: C (diamond, graphite), SiO2 (quartz)

Question 6

Metallic Properties

Answer 6

Properties: variable hardness, and melting points, it DOES conduct electricity, conducts heat, is lustrous (shiny), malleable, ductile
Forces: metallic bonding
Ex: Fe, Mg
