A hard, brittle solid has a high melting point and conducts electricity only after it melts. Which bonding type best matches?
A shiny solid conducts electricity as a solid and can be hammered into thin sheets. Which bonding type explains these properties?
A molecular substance has a low boiling point and does not conduct electricity in any state. Which bonding category is most likely?
A white crystalline solid dissolves in water, and the solution conducts electricity. What type of bonding is most likely in the solid?
A gray solid bends without shattering and carries current through a wire at room temperature. Which bonding type fits?
A gas at room temperature forms separate molecules and has a very low melting point. Which bonding type is most likely inside its particles?
A solid shatters when struck and does not conduct electricity until dissolved in water. Which bonding type is most likely?
A silver-colored strip has a high melting point, conducts heat well, and can be drawn into a wire. What type of bonding does it show?
Table sugar, C12H22O11, dissolves in water, but the solution does not conduct electricity. Which bonding type is most likely in sugar?
Two elements have electronegativities of 1.0 and 4.0. Which bonding type is most likely in the compound they form?
Mercury, Hg, is a liquid at room temperature, yet it conducts electricity. Which bonding type holds the mercury atoms together?
Quartz, SiO2, is very hard and melts above 1600 °C, but it does not conduct electricity as a solid or when melted. Which bonding type holds its atoms together?
A crystal is hard but breaks along flat planes, and its solid form is an electrical insulator. Which bonding type best fits?
Sodium, Na, is soft enough to cut with a knife, yet a freshly cut piece is shiny and conducts electricity. Which bonding type holds the sodium atoms together?
Ethanol, C2H5OH, is a liquid at room temperature. Which bonding type holds the atoms together within each ethanol molecule?
A solid compound has charged particles held in fixed positions, but when the solid melts, those particles move and carry current. Which bonding type is this?
Electrons are transferred from sodium atoms to chlorine atoms, producing Na+ and Cl-. What type of bonding is described?
Positive metal ions are surrounded by a mobile sea of valence electrons throughout a solid. Which bonding category is described?
Two chlorine atoms each contribute one electron to make a shared pair between them. Which bonding type is this?
Layers of positive ions slide past one another while mobile valence electrons keep holding them together, so the solid bends instead of shattering. Which bonding type is this?
A magnesium atom loses two electrons, and each bromine atom gains one electron before the particles attract. Which bonding type forms?
Several atoms in a molecule reach stable valence shells by sharing bonding pairs rather than forming ions. Which bond type is described?
Atoms in a solid release valence electrons into a shared pool, helping explain why the solid conducts electricity. Which bond type is this?
A metal atom gives electrons to a nonmetal atom, and the resulting charged particles attract in a lattice. What bonding type is described?
