which of these types of bonds allows electrons to move freely among the atoms?
metallic
polar covalent
ionic
nonpolar covalent
which of these substances contains positive ions immersed in a sea of electrons?
O₂ (s)
SiO₂ (s)
Cu (s)

a solid substance is an excellent conductor of electricity. the chemical bonds in this solid substance are most likely:
ionic, because the valence electrons are shared between atoms
ionic, because the valence electrons are mobile
metallic, because the valence electrons are stationary
metallic, because the valence electrons are mobile
Lewis dot diagrams for sodium (Na) and chlorine (Cl) are shown in the attached diagram. Which of the following best describes what will happen with these two elements forming a bond?
Sodium and chlorine will share their valence electrons
Sodium gains seven electrons and chlorine will gain one electron
Sodium will lose one electron and chlorine will gain one electron
Sodium will gain seven electrons and chlorine will lose one electron
Lewis dot diagrams are shown for lithium (Li) and chlorine (Cl) in the attached photo. If these atoms form a bond, what will happen to their electrons?
Lithium will gain one electron and chlorine will lose one electron.
Lithium will lose one electron and chlorine will gain one electron.
Lithium will gain seven electrons and chlorine will lose one electron.
Instead of transferring their electrons, lithium and chlorine will share their electrons so that both atoms may obtain a full valence shell.

In the diagram attached, the electrons are not attached to a specific nucleus, but are able to freely move and flow throughout the mass. What kind of bonding is this a representation of?
Covalent
Ionic
Metallic
Hydrogen
Which of these best describes the bonding that happens among the atoms in a sample of copper?
