3.1.3.4 Bonding and physical properties- Malleability Flashcards
how the bonding and structure lead to the typical metallic property of malleability
cations / positive ions / atoms in the lattice are all identical / the same size / (planes of) ions (atoms) can slide easily over one another
attractive forces in the lattice are the same whichever ions (atoms) are adjacent / attractive forces remain the same throughout the lattice
Why graphite is soft
Planes
weak (bonds) forces between planes
why nickel is ductile (can be stretched into wires)
Layers / planes / sheets of atoms or ions can slide over one another
why titanium can be hammered into different shapes
Layers of atoms/ions slide (over one another)
why sodium metal is malleable (can be hammered into shape)
Layers can slide over each other – idea that ions/atoms/particles move
