The metallic model

Contrast tin and tin(IV) iodide in terms of one physical property.

Which list arranges the metals in order of increasing strength of metallic bonding (weakest first)? A. Rb, Mg, Na, Al B. Al, Mg, Na, Rb C. Rb, Na, Mg, Al D. Na, Rb, Al, Mg

State one other physical property that could be measured to identify the metal while leaving the block intact.

Which statement best explains why aluminium can be drawn into thin wires? A. The delocalized electrons carry charge through the metal. B. The layers of aluminium ions can slide over each other while the delocalized electrons keep the lattice bonded. C.…

In which set do all the species contain delocalized electrons? A. $\ce{NH4+}$, $\ce{C6H12}$, $\ce{Si(s)}$ B. $\ce{CH3OH}$, $\ce{SO2}$, $\ce{C}$ (diamond) C. $\ce{C2H4}$, $\ce{NO3-}$, $\ce{SiO2}$ D. $\ce{CO3^2-}$, $\ce{C6H6}$, $\ce{Cu(s)}$

Copper can be hammered into thin sheets without shattering. Which feature of metallic bonding explains this? A. The delocalized electrons are free to move through the lattice, carrying charge. B. The metallic bonds are weak, so the cations are easily displaced…
