Explain why the reactivity decreases down group 7 - the difference in the electrons:
going down the group, the atoms get
bigger
outer electrons are
further
from nucleus
attraction between
negative
electrons and
positive
nucleus are
less
strong
Explain why the reactivity decreases down group 7 - the difference in reactivity:
group 7 elements react to become ions with
1-
charge. this means they
gain
1 electron
down the group, there is
less
attraction for the
outer
electrons
means that the elements gain electrons
less
easily
Describe experiment A:
Chlorine
displaces the
bromide
ions in NaBr. This leads to the
formation
of
bromine
which is orange
Describe experiment B:
There are no observations in experiment B because
bromine
cannot
displace
the
chlorine
ions in NaCl.
Explain the results:
This is because
reactivity
decreases
down
group
7.
Bromine is
lower
down than chlorine and therefore is
less
reactive and cannot displace.
