1. Periodic Table Intro

2. Facts About The Table
Who developed it? When and how?: In the year 1869, the Russian chemist Dmitri
Ivanovich Mendeleyev (1834-1907) developed the periodic table, He did it to teach his
students and published it in “Principles of Chemistry”. The periodic table is the table in
which chemical elements are arranged by their atomic numbers.

3. How Was It Arranged?
Mendeleev arranged the elements in a manner somewhat similar to the grouping of cards
by order and suit in solitaire, and he eventually drafted his chart according to a principle
of rows of increasing atomic weight, which also put elements with similar properties in
the same vertical columns.

4. What Are The Element’s
Relationships With Each Other?
There relationships include the outcomes of cross contamination and their atom levels.
In some groups, the elements have very similar properties and exhibit a clear trend in
properties down the group - these groups tend to be given trivial (unsystematic) names,
e.g. the alkali metals, alkaline earth metals, halogens and noble gases. Some other groups
in the periodic table display fewer similarities and/or vertical trends (for example Groups
14 and 15), and these have no trivial names and are referred to simply by their group
numbers.

5. Examples Of Elements
Cu Example: Copper in the wiring, atomic number 29, atomic mass: 63.546 ± 0.003
Aluminum: Example: Al in pots and pans, atomic number: 13, atomic mass: 26.981539 ±
0.0000008 u
Iron: Example: Fe in various, atomic mass: 55.845 ± 0.002 u, atomic number: 26
Chromium: Example: Cr in anything chrome-plated. Atomic number: 24, atomic mass:
51.9961 ± 0.0006
