Block (periodic table) valence electrons, and, except for helium, are only slightly less reactive. The p-block is on the right side of the periodic table and includes elements from the six columns beginning with column 13 and ending with column 18. Helium, though being in the top of group 18, is not included in the p-block.General valance configration is ns np1-6. The p-block COB This contains variety of elements and is the only block that contains all three types of elements: metals, nonmetals, and metalloids. Generally, the p-block elements are best described in terms of element type or group. P-block elements are unified
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."
