What explains the typical features of metals such as shininess and conductivity?

• The structure of metals and the nature of metallic bonds

• The presence of ionic bonds

• The arrangement of covalent bonds

• The isolation of metals from non-metals

What is the nature of metallic bonding?

• A collection of cations surrounded by a mobile sea of electrons

• A collection of anions surrounded by a stationary sea of protons

• Oppositely charged ions held together by electrostatic attraction

• Two uncharged atoms sharing their valence electrons

Why are metals good conductors of heat and electricity?

• Because of the stationary sea of electrons

• Due to the sharing of valence electrons

• Due to the free flow of electrons

• Because of the strong ionic bonds

What property of metals allows them to be hammered into thin sheets without breaking?

• Ductility

• Ionic bonding

• Covalent bonding

• Malleability

Which metal is known as the most malleable?

• Copper

• Iron

• Gold

• Silver

What makes metals ductile?

• The ability to be pulled into long thin wires

• The ability to shatter like ionic crystals

• The stationary sea of electrons

• The presence of covalent bonds

Which of the following metals is liquid at room temperature?

• Platinum

• Mercury

• Gold

• Iron

What is responsible for the shininess of metals?

• The highly mobile sea of electrons

• The presence of ionic bonds

• The arrangement of covalent bonds

• The isolation of metals from non-metals
