  • The periodic table of elements. A color-coded grid with letters representing each element. Caption: Each row of the table represents a pattern of chemical properties

    As scientists discovered more and more chemical elements, they began developing systems to organize the elements by their chemical properties, leading to the modern periodic table. Through its organization, the periodic table makes clear the underlying chemical and physical trends among the elements. The periodic table is being continually updated even today as scientists strive to create new elements in laboratories. Part of the series Chemistry: Challenges And Solutions.

  • Cluster of molecules. Caption: are added together to get the mass number.

    Part of the "Chemistry in Action" series. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional strategies. Specific patterns in the periodic table are highlighted. Introduces the following terminology: atomic structure, atomic number, atomic mass, periods, and families.

  • Illustration of an atom showing the nucleus and orbiting electrons. Caption: has a maximum number of electrons it can hold.

    It's called a theory, but if we have never seen an atom, how did anyone ever come up with an idea that is so central to science. Shows how all the pieces of the puzzle have come together at the same time, explaining the structure of the atom and the periodic table.

    3D model of the atom Carbon

    Carbon (from Latin: carbo "coal") is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group 14), which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent - making four electrons available to form covalent chemical bonds. Three isotopes occur naturally, 12C and 13C being stable while 14C is radioactive, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.
