2. Period 6 element - Wikipedia

   en.wikipedia.org/wiki/Period_6_element

   A period 6 element is one of the chemical elements in the sixth row (or period) of the periodic table of the chemical elements, including the lanthanides.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements ...

   Overall score: 1st--15, 2nd--12, 3rd--10, 4th--8, 5th--6, and 6th--4. In addition, the school with the top scorer in a subsection receives 3 points. A school can earn multiple subsection points even if the same student is the top scorer in two, or all three, of the subsections. Team places: 1st--10 and 2nd--5.

4. List of chemical elements - Wikipedia

   en.wikipedia.org/wiki/List_of_chemical_elements

   118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).

5. Period (periodic table) - Wikipedia

   en.wikipedia.org/wiki/Period_(periodic_table)

   A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.

6. Periodic table - Wikipedia

   en.wikipedia.org/wiki/Periodic_table

   For reasons of space, [30] [31] the periodic table is commonly presented with the f-block elements cut out and positioned as a distinct part below the main body. [32] [30] [23] This reduces the number of element columns from 32 to 18. [30] Both forms represent the same periodic table. [6]

7. Group 6 element - Wikipedia
