Below are sample questions representative of the exercises included on this worksheet and related 11.38 Metallic Bonding, Alloys, and Conductivity skill assessments:

Problem 1Difficulty: Mastery

Which statement best integrates metallic bonding, conductivity, and alloy design?

AMetals conduct through moving protons, and alloying works only by removing all electrons.

BMetals are brittle ionic crystals, and alloying makes them pure molecular solids.

CMetals conduct only when dissolved, so solid alloy structure has no effect.

DMetals conduct through delocalized electrons, and alloying can adjust properties by changing how ion cores are arranged around those electrons.

Solution & Explanation:The key model is that delocalized electrons give metallic conductivity, while changes to the lattice in alloys can modify strength, ductility, corrosion resistance, and conductivity.

Problem 2Difficulty: Mastery

A coin alloy contains gold and copper. Compared with pure gold, the alloy is harder and less easily bent. Which explanation is best?

ACopper atoms remove every delocalized electron, so no metallic bonding remains.

BGold becomes a salt because copper atoms donate electrons to chloride ions.

CCopper atoms disrupt the gold lattice and hinder the smooth sliding of metal layers.

DPure gold is harder because its atoms are all different sizes.

Solution & Explanation:Adding copper changes the arrangement of atoms in the gold lattice. This can increase hardness by making layer sliding more difficult.

Problem 3Difficulty: Mastery

A diagram shows electrons drifting through a metal wire when a battery is connected, while positive ion cores remain in place and vibrate. Which interpretation is best?

AThe diagram shows ionic conduction by positive ions moving through water.

BThe diagram models metallic conduction by mobile electrons through a fixed lattice of ion cores.

CThe diagram shows covalent molecules breaking apart into gases.

DThe diagram shows protons leaving nuclei to carry current.

Solution & Explanation:The visual matches the metallic conduction model: electrons are mobile charge carriers, and ion cores mainly vibrate in lattice positions.
