Block (periodic table) the s-block, with its outer (and only) electrons in the 1s atomic orbital, although its chemical properties are more similar to the p-block noble gases due to its full shell. In addition to the blocks listed in this table, there is a hypothetical g-block which is not pictured here. The g-block elements can be seen in the expanded extended periodic table. Lanthanum and actinium are placed under scandium and yttrium to reflect their status as d-block elements, as they have no electrons in the 4f and 5f orbitals, respectively, while lutetium and lawrencium do. The s-block is on the left
Alphabetical order looke in the beginning of this Table, but if with (v) looke towards the end." Although as late as 1803 Samuel Taylor Coleridge condemned encyclopedias with "an arrangement determined by the accident of initial letters", many lists are today based on this principle. The standard order of the modern ISO basic Latin alphabet is: An example of straightforward alphabetical ordering follows: Another example: The above words are ordered alphabetically. "As" comes before "Aster" because they begin with the same two letters and "As" has no more letters after that whereas "Aster" does. The next three words come after "Aster" because
