Metal Properties Flashcards
What does Malleable mean
Able to be molded into a new shape
Generally, all metals can conduct electricity
True
What properties represents “shiny’
Lustrous
Why are metals able to conduct electricity
The sea of electrons helps pass charges through the metal
When a metal is cooled down from its liquid form
The lattice begins to form in various places at once
If a piece of metal is heated and then rapidly cooled in water. Would it be easier or harder to snap
Quenching and brittle so it will be easier to snap
Define and explain the processes of quenching, annealing and tempering
heating the material to a high temperature, then cooling it rapidly (quenching), followed by reheating it to a lower temperature (tempering) and heating slow and cooling slow is (annealing).
Explain why only metallic elements form metallic bonds
Metallic stricture, electron delocalization and properties of metallic bonds
What is the structure of a metallic lattice
All in a line
Why do the crystals in a piece of metal contribute to the metal properties
The mobility of the electrons is also what allows metallic solids to be good electrical conductors.
What happens to the crystals when the metal is heated and cooled immediately
Iron-based alloys can be hardened if heated to a high enough temperature
Using metallic bonding why are metals good conductors of heat
Metals have free electrons that are not bounded to the atoms
Using metallic bonding why do metals generally have a high melting point
because of the strong electrostatic attraction that exists between their cations and delocalized electrons
Using metallic bonding why are metals malleable
electrons are delocalized and move freely among nuclei
Compare potassium and sodium to describe what affects the reactivity of a metal
The less electrostatic attraction
