This quiz contains 13 questions from a mix of 1 subtopics.
What factors affect the strength of a metallic bond?
(Select all that apply).
charge on the metal ion
radius of the metal ion
mass of the metal ion
shape of the metal ion
|
Which metal has the lowest melting point?
lithium
beryllium
sodium
magnesium
|
Which metal has the highest melting point?
lithium
beryllium
sodium
magnesium
|
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).
low strength
malleable
high melting points
unable to conduct electricity
|
Metals conduct electricity due to the sea of electrons.
|
Giant metallic structures have melting points because there are metallic bonds between cations and delocalised electrons which require a lot of energy to break.
|
What type of crystal structure has delocalised electrons?
metallic
ionic
simple molecular
|
Why can metals conduct electricity?
molecules can flow through the structure and carry electrical charge
delocalised electrons can flow through the structure and carry electrical charge
metal ions can flow through the structure and carry electrical charge
|
Predict the most likely crystal structure of a substance which has a melting point of 660°C and which conducts electricity in the solid and liquid states.
metallic
giant covalent
ionic
simple molecular
