The periodic table of chemical elements, created by Dmitry Mendeleev in 1869, is one of the most important achievements in modern science. To celebrate this achievement, BLS has created our own periodic table! Instead of elements, we have used Science, Technology, Engineering and Math (STEM) occupations. Workers in STEM occupations use science and mathematics to understand how the world works and to solve problems. Hover over an "element" or group to highlight that discipline.

The PDF file contains three blank periodic tables useful for student work. One contains only symbols and you need to write in the names of the elements, in the other the situation is reversed. The third one is completely empty.
This pictorial periodic table is colorful, fun, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings. Small symbols pack in additional information: solid/liquid/gas, color of element, common in the human body, common in the earth's crust, magnetic metals, noble metals, radioactive, and rare or never found in nature. It does not overload kids with a lot of detailed numbers, like atomic weights and valence numbers.
This textual periodic table is packed with even more information. In addition to the element's name, symbol, and atomic number, each element box contains a textual description of the element's physical properties and a list of several of its human uses and/or natural occurrences. The table is color-coded to show the chemical groups, and each group is described in a panel of the same color. Other info panels describe atomic structure, chemical bonding, and radioactivity. It does not overload kids with a lot of detailed numbers, but it does provide some simple rules-of-thumb about atomic weights and valence numbers.
Print-your-own elements cards. Use these however you want. It's fun to simply lay them out to make the whole periodic table. You can use them as flash cards to help you memorize the facts on the front and back of each card. If you want to play it as a game, you can invent your own game rules.
This color-coded chart shows what atoms look like. This chart shows all the fundamental atomic electron orbitals as electron probability density distributions (fuzzy clouds), which is close as you can get to visualizing what an atom really looks like. The orbitals are labeled. It describes other ways to visualize atoms, namely, electron orbits (like planets) and surfaces of constant probability (bulgy blobs). It has a small periodic table showing in which order the electron shells are filled.
The periodic table also referred to as the periodic table of elements, is specifically a tabular display of the chemical elements, which are arranged by their atomic numbers, electronic configuration, and recurring chemical properties. The structure and shape of the table show periodic trends of the elements. The seven rows of the table, which are called periods, usually have metals on the left and nonmetals on their right side. The columns are called groups that contain elements with similar chemical behaviours and attributes. Six groups have designated names and assigned numbers: for instance, group 17 elements are the halogens; and group 18 elements are the noble gases.
In response to Amanda Reig's request on Facebook, I'm starting a discussion forum where we can share periodic table files in a variety of formats. I have included two Word versions in portrait and landscape mode as well as an Excel file. These files can get manipulated to fit on a credit card.
I'm finally getting around to uploading my image files for wallet sized periodic tables. I took the word document above and shrunk the fonts considerably, exported to pdf, then shrunk again in my graphics software (I used GIMP, which is a freeware program similar to photoshop). The quality came out fantastic. I've attached both a pdf and jpg file of the periodic table we used.
I wonder if anyone has a good periodic table for a LaTeX document (besides an image). I am migrating to LaTeX since Word removed the equation editor I depended on for so much..... (LaTeX has some fantastic features that allow chemical structures and other things-- Perhaps this could be a forum?)
Several methods are available for producing thorium metal; it can be obtained by reducing thorium oxide with calcium, by electrolysis of anhydrous thorium chloride in a fused mixture of sodium and potassium chlorides, by calcium reduction of thorium tetrachloride mixed with anhydrous zinc chloride, and by reduction of thorium tetrachloride with an alkali metal. Thorium was originally assigned a position in Group IV of the periodic table.
A good periodic table is a necessary part of every chemist's, or future chemist's, reference materials. After looking around for a useful printable periodic table, I found that most were pretty basic and included only a few properties. So, we set out to create a periodic table using Excel that would include as many of the important chemical and physical properties as we could reasonably fit on a single piece of 8 1/2 x 11" paper.
The following two PDF files can be downloaded and printed on normal 8 1/2 x 11" paper (in landscape orientation) - perfect for including in a 3-ring binder. You will need to use a nice laser printer because the text is quite small. You may print and distribute as many paper copies of these periodic tables as you want to, as long as they are printed as-is. Note that photocopies don't turn out well. You should print directly from the original PDF.
This spreadsheet was used to create the printable periodic table above and also contains a worksheet listing the data for various chemical properties. If you'd like to create your own personal custom periodic table, you can download this Excel file and add your own sets of properties.
The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviors.
Modern Period Law: The physical and chemical properties of elements are the periodic function of their atomic number.Modern periodic table is based on atomic number of elements.Atomic number (Z) is equal to the number of protons present in the nucleus of an atom of an element.Modern periodic table contains 18 vertical column known as group and seven horizontal rows known as periods.On moving from left to right in a period, the number of valence electrons increases from 1 to 8 in the elements present.On moving from left to right in a period, number of shell remains same.All the elements of a group of the periodic table have the same number of valence electrons.
(iii) Metallic and Non-Metallic properties: In the modern periodic table metals are on the left side and non-metals on the right side of the table. A zig-zag line of metalloids separates metals from non-metals.
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
Although Mendeleev's table demonstrated the periodic nature of the elements, it remained for the discoveries of scientists of the 20th Century to explain why the properties of the elements recur periodically. For example, in 1911, A. van den Broek in a series of two papers proposed that the atomic weight of an element was approximately equal to the charge on an atom. This charge, later termed the atomic number, could be used to number the elements within the periodic table. With the discovery of isotopes of the elements, it became apparent that atomic weight was not the significant player in the periodic law as Mendeleev, Meyers and others had proposed, but rather, the properties of the elements varied periodically with atomic number. The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded the Nobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.
The Periodic table is useful for modern students and scientists because it helps predict the types of chemical reactions that a particular element is likely to participate in. Rather than memorize facts and figures for each element, students and scientists need only glance at the table to learn much about the reactivity of an element, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics. Another useful feature of the periodic table is that most tables provide all the information you need to balance chemical reactions at a glance. The table tells each element's atomic number and usually its atomic weight. The usual charge on an element is indicated by an element's group.
