Notes
The periodic law defines the
repeating physical and chemical
properties of elements change
periodically with atomic
number. Valence electrons are
found in the outermost shell of
the atom and determines the
chemical properties.
The physical basis of
the periodic table
How can you tell if
a chemical element
will bond with
another?
Investigation
j. …statistical
variability and the
need for controlled
tests.

The shape of the PT is
determined by how electrons
fill orbital's. Only the __ and
__ electrons shown
individually because unlike
___ and ___ electrons, they fill
sequentially.
A. What led Mendeleev to
predict that some elements
had not yet been
discovered?
B.
What do elements in the
same period have in
common?
C. What do elements in the
same group have in
common?
D. Name the element
symbol and the atomic
number of Gold, Lead,
Silver, Copper.
E. Why can period 1 have a
maximum of two elements?
F. What determines the
number of elements found
in each period in the PT?
G. How many valence
electrons does Carbon
have?
