What is the general
trend for melting
points in group 2
and why is it this?
2.2.1
inorganic
ZQ
,Group 2 elements have high
melting points, this is
because:
• they have a giant metallic
lattice structure
• which contains many
strong metallic bonds,
which require lots of energy
to break
,What is the general
trend for density in
group 2 compared
to group 1 and why
is it this?
2.2.1
inorganic
ZQ
, Group 2 elements are
harder and have a higher
density than group 1
elements, this is because:
• the group 2 ions are
smaller than group 1 ions
• so they pack more
closely together
