With an easy to follow structure and colour coding, Benfey’s spiral or “snail”, illustrates the elements in a more engaging way. $\endgroup$ – bon Apr 16 '15 at 8:56 $\begingroup$ This is an answer to another question that was labeled a duplicate and closed.

Dmitri Mendeleev published a periodic table of the chemical elements in 1869 based on properties that appeared with some regularity as he laid out the elements from lightest to heaviest. The periodic table of elements is so familiar to us that we tend to assume that it fell from heaven in the form in which it is traditionally displayed. BBS is the internationally renowned journal with the innovative format known as Open Peer Commentary.

ADOMAH periodic table (horizontal) - electron orbitals.svg 3,700 × 1,160; 37 KB. The latest addition to this multi-story table is the aluminium cluster ion Al−7, which behaves like a multivalent germanium atom. Figure 4. The ADOMAH table is an adaptation of the left step table. Click on the icons below to see full-sized versions of the tables. In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair. A period 1 element is one of the chemical elements in the first row of the periodic table of the chemical elements. The periodic table is an arrangement of the chemical elements, structured by their atomic number, electron configuration and recurring chemical properties. Sort by rank ; Recent popularity; Recently added; Filter by tags. In March 1869, Russian scientist Dmitri Mendeleev arranged all known chemical elements into a table, in rows of atomic number from left to right. In an uncharged atom, the atomic number is also equal to the number of electrons. Common Properties Abundance in Earth's Crust [1] [2]. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the 1s orbital. Alternatives to the Periodic Table. Usually, when we think of the elements, we picture them in the tabular format of which Mendeleev had the original idea. Transition elements are integrated with all the other elements. Major alternative structures Left step periodic table (Janet, 1928) Charles Janet's Left Step periodic table (1928) is considered to be the most significant alternative to the traditional depiction of the periodic system. Let’s take a look at some of the most memorable versions. Each block of elements has the same value of the secondary quantum number l. For example, l = 2 for Fe. The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their recurring properties. For example, the electron configuration of Fe is determined by starting at H, which is 1s1, and counting in atomic number order. Some of the designers responsible for these new versions thought the tabular form had limitations that they wanted to improve upon; others wanted to make the elements easier to comprehend or accommodate for new discoveries. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms, because most chemical properties are dominated by the orbital location of the outermost electron. “I thought the spiral had more potential to show the interrelations of the elements than the Periodic Table,” he said.
