what are the general physical properties of transition metals?
malleable
ductile
good conductors of electricity
shiny when polished
why is iron useful in construction?
iron is malleable and strong, making it ideal for buildings, bridges, ships, and cars
why is copper used for electrical wiring?
copper is ductile and a good conductor of electricity, making it ideal for electrical wiring
what is a use of silver?
silver is shinier than aluminium, making it an excellent reflective coating for mirrors in infrared telescopes
how do transition metals compare to group 1 and 2 metals?
they have:
higher melting points
higher densities
than group 1 and 2 metals
what is an exception to the typical physical properties of transition metals?
mercury is a transition metal with a high density, but is liquid at room temperature
what are the chemical properties of transition metals?
they form coloured compounds
they show catalytic activity
what transition metal is used as a catalyst in the haber process?
iron is used as the catalyst to manufacture ammonia in the haber process
catalytic converters in vehicles convert harmful exhaust gases into less harmful ones. suggest a reason that explains why these devices contain platinum and rhodium
platinum and rhodium are transition metals. transition metals show catalytic activity and so increase the rate of reaction without being changed chemically or in mass by the end of the reaction.
