The periodic table orders elements by increasing atomic number, which is the number of protons in the atom of an element. The rows of the periodic table are called periods. All elements within a period share the same highest electron energy level. The columns of the periodic table are called groups. All elements in a group share the same number.
The Royal Society of Chemistry's interactive periodic table features history, alchemy, podcasts, videos, and data trends across the periodic table. Click the tabs at the top to explore each section. Use the buttons above to change your view of the periodic table and view Murray Robertson’s stunning Visual Elements artwork.
Development of the periodic table (part of a collection of pages that explores the periodic table and the elements) by the Royal Society of Chemistry; Dr. Eric Scerri's web page, which contains interviews, lectures and articles on various aspects of the periodic system, including the history of the periodic table.

Help your students grasp the fundamentals of the periodic table, its function and features, and why it’s an essential part of understanding Chemistry with a bit of help from Beyond.
Periodic table is a tabular chart of the elements arranged to illustrate recurring trends in the properties of the elements. Elements are listed according to increasing order of atomic number in columns and rows. Rows, also called periods, are arranged so that elements with similar properties fall into the same columns, called groups or family.
Figure 2.2: (Upper Panel) The Periodic Table of the Elements is an organized chart that contains all of the known chemical elements.(Lower Panel) To the left of the arrow is shown one atom of oxygen and two atoms of hydrogen.Each of these represent single elements. When they are combined on the righthand side, they form a single molecule of water (H 2 O).
Crossword on the theme of 'The Periodic Table'. Powerpoint so can be used on the board or printed as a worksheet. Includes space for students to explain the keywords and suggested extension activities. Can take 10 minutes or an hour, depending on which activities the students complete. Ideal for the start of a lesson, a quick filler, a homework, part of a cover lesson or as a plenary on the.
As we move past the first eighteen elements, you can start to learn about transition elements in the fourth period (row) of the periodic table.The transition metals have electron configurations that are a little different from the first eighteen. Make sure you understand the basics of electron orbitals before you move on to this row.
After doing the partner practice on the first section students find the second part easier, and I encourage them to try the questions on their own first and then ask their table partners or myself for help if they are stuck. If students do not complete the second half I have them complete for homework.
