Periodic  Periodic Law  Periodic Table
• Something periodic occurs at regular or at
least generally predictable intervals
• Periodic law - physical and chemical
properties of the elements are periodic
functions of their atomic numbers
• Periodic Table of Elements – a table of
the elements, arranged by atomic number,
that shows the patterns in their
properties; based on the periodic law
Can you think of anything that is periodic?
Element
• A pure substance made up of one kind of
atom that cannot be broken down into
simpler substances by physical or
chemical means
• 90 occur naturally on earth
• 25 were synthesized (made) by scientists
http://www.privatehand.com/flash/elements.html
Dmitri Mendeleev
• In the 1860’s he
devised a periodic
table where the
elements were
ordered by their
atomic masses
• He did this by
grouping elements
together according to
their similarities
• Draft of Mendeleev's
Periodic Table

Mendeleev’s Published Periodic Table of Elements
Why do you think there are question marks here?
Image taken from: http://www.chemsoc.org/networks/learnnet/periodictable/post16/develop/mendeleev.htm
Mendeleev’s Predictions
• Although Mendeleev’s Periodic Table of Elements
had missing elements or “gaps,” he was able to
predict the characteristics of these missing
elements because of Periodic Law.

Henry Moseley
• In 1914, his work led
to a revision of the
periodic table by
rearranging the
elements by their
atomic numbers
• He concluded that the
number of protons in
an atom is its atomic
number

the periodic table
(exception  Hydrogen)
Chemical Properties
• Have few electrons in
their outer energy level,
thus lose electrons
easily
Physical Properties
• ductile, good
conductors, malleable,
shiny, most are solid @

FROM LEFT TO RIGHT OR RIGHT TO LEFT
How many
periods
(rows)
are on the
Periodic
Table
Of
Elements?
Period (Row) Properties
• Seven periods on a periodic table (numbered
from the top down)
• Atomic numbers and atomic masses increase as
you move from the left to the right in a period
• All atoms of the elements in the same period
have the same number of orbitals/levels
• All atoms of the elements in a specific period
have that respective number of orbitals/levels
– Example
• Period 1 = 1 orbital
• Period 2 = 2 orbitals
• Period 3 = 3 orbitals
• Etc…

FROM TOP TO BOTTOM OR BOTTOM TO THE TOP
Group (Family) Properties
• Eighteen groups on the periodic table (numbered
from left to right)
• Atomic numbers and atomic masses increase as
you move from the top down in a group (family)
• Atoms of elements in the same group have the
same number of electrons in the outer
orbitals/levels of their atoms (known as valence
electrons)
– Exceptions:
• Transition elements (3-12)
• Hydrogen (could be 1 or 17)
• Helium (actually has 2 valence electrons)
• Elements in groups usually have similar physical
and chemical properties
Examples of Group Elements with the
same # of valence electrons
How many electrons do
each of these atoms have
in their outer
orbital/level?
