As
atomic mass increases
,
melting point
,
boiling point
, and
density increase
due to
stronger forces
of
attraction
Reactivity of non-metals
decreases
as atomic mass increases
More shielding
-
more shells
Outer shell further away
from the
nucleus
Weaker force
of
attraction
between
positive nucleus
and
negative electrons
Harder
to
gain electrons
to the
outer shell
Reactivity
of
metals
increases as
atomic mass
increases
Easier to lose
electrons
as they are further away from the
positive nucleus
- more
shielding
due to more
shells
