Question:
How
are
elements
organized
on
the
periodic
table,
and
how
does
this
organization
relate
to
the
periodic
properties?
What
information
is
given
in

atom,
this
is
called
the

The
horizontal
rows
on
a
periodic
table
are
called
periods.
As
you
move
from
left
to
right
across
a
period…
• The
number
of
protons
increases
• The
number
of
valence
electrons
increases
by
1
• Atomic
size
(volume)
decreases

and
why?
If
an

than
protons
it
is
called

isotope.
If

is
now
called

cation.
If
an
element
gains
an
electron
it
has
a
negative
charge
and
is
called
an
anion.
