Ionic, covalent & metallic bonding Flashcards
What does this property tell us about the structure of metals?
Metals are usually hard and tend to have high boiling points.
The forces between the particles must be strong.
What does this property tell us about the structure of metals?
Metals conduct electricity in solid and molten liquid state.
Metals have charged partials that are free to move.
What does this property tell us about the structure of metals?
Metals are malleable and ductile.
The attractive forces between the particles must be stronger than the repulsive forces between the particles when the layers of particles are moved.
What does this property tell us about the structure of metals?
Metals generally have high densities.
The particulars are closely paced in a metal. The density of a metal depends on the mass of their ions, their radius and the way they are packed in the lattice.
What does this property tell us about the structure of metals?
Metals are good conductors of heat.
When delocalised electrons bump into each other and the metal ions they transfer energy. Heating a metal gives the ions and electrons more energy to vibrate more rapidly, transmitting the heat through the lattice.
What does this property tell us about the structure of metals?
Metals are lustrous or reflective.
Free electrons are present, so metals can reflect light of all wavelengths and appear shiny.
What does this property tell us about the structure of metals?
Metals tend to react by loosing electrons.
Electrons must be relatively easily removed from metal atoms.
