topic 4 - properties of metals Flashcards
are most of the elements metals or non-metals?
metals
where are non-metals found?
right hand side of the periodic table
where are the transition metals found?
centre block of the periodic table
what are two typical properties of metals?
malleable(bendy) and good conductors
what similar properties do transition metals have?
as well as normal metal properties they have high melting and form very colourful compass
what gives metals their properties?
their structure
what type of bonds do metals have?
metallic bonds
what kinds of arrangement do metals have?
a regular arrangement
what structure do metals have?
the metallic bonds give the metal a giant structure
what does a metals giant structure consist of? why?
positive ions and free electrons because metallic bonds allow the outer electrons to become delocalised
why are metals good conductors of electricity?
because metallic bonding allows the outer electrons to move freely which creates a “sea” of delocalised electrons so the electrons can move freely through the structure of the metal
do metals have low or high melting and boiling points?
extremely high because they have a giant structure with strong metallic bonds
are metals insoluble?
yes
why are metals malleable?
they have layers of atoms to slide over each
what are group 1 metals called?
alkalis
