Metals can bind to non-metals via bonding, whereby particles with opposite charges are attracted to each other. Non-metals can bind to other non-metals via bonding, whereby electrons are shared. Metal atoms can bind to other metals using bonding.
|
The crystal structure of a metal is known as a g m l.
|
In metallic bonding, electrons are delocalised from the lattice of metal ions. These electrons can carry charge, and so metal acts as a conductor of . These electrons can also carry energy, meaning metals are good conductors of heat.
|
In metallic bonding, each metal atom becomes an ion with a charge. It does this by giving up its outer shell electrons. These electrons are said to be '', and are shared across all the ions in the structure.
|
Which of the following are properties of metals?
(Select all that apply).
unable to conduct electricity
low strength
malleable
high melting points
|
Which metal has the highest melting point?
lithium
beryllium
sodium
magnesium
|
Which metal has the lowest melting point?
lithium
beryllium
sodium
magnesium
|
What factors affect the strength of a metallic bond?
(Select all that apply).
radius of the metal ion
mass of the metal ion
shape of the metal ion
charge on the metal ion
|
Giant metallic structures have melting points because there are metallic bonds between cations and delocalised electrons which require a lot of energy to break.
