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
The Periodic Table (Basher book) get people engaged is to make it accessible while still presenting hard facts and knowledge," while Basher was concerned that the book's design be "sharp and focused" in order to "connect with today's visually advanced young audience." "Publishers Weekly" said that the book was a "lively introduction to the chart that has been the bane of many a chemistry student", and in a review in "New Scientist", Vivienne Greig called "The Periodic Table" "an engrossing read and an ideal way to painlessly impart a great deal of science history to seen-it-all-before teenagers."
