ATOMIC RADIUS


Along a period :
atomic radius decreases
. The increased nuclear charge (for
the same no of shells) increases the attraction from the nucleus and pulls
the outer shell electrons closer to the nucleus
.


NISATION
ENERGY

Along a
period
:
isnisation energy increases
. As the atomic radius decreases
and nuclear charge increases ,
the attraction between the nucleus outer
shell electrons increases and :· the electrons are held more strongly
. This
means that more energy is required to remove the outer electron & ionise
the atom
.
