Block (periodic table) in the extended periodic table whose outermost electrons are posited to include one or more g-orbital electrons. Block (periodic table) A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are: The block names (s, p, d, f and g) are derived from the spectroscopic notation for the associated atomic orbitals: sharp, principal, diffuse and fundamental, and
The Periodic Table (Basher book) The Periodic Table (Basher book) The Periodic Table: Elements with Style is a 2007 children's science book created by Simon Basher and written by Adrian Dingle. It is the first book in Basher's science series, which includes "Physics: Why Matter Matters!", "Biology: Life As We Know It", "Astronomy: Out of this World!", "Rocks and Minerals: A Gem of a Book", and "Planet Earth: What Planet Are You On?", each of which is 128 pages long. The book is arranged in eleven chapters plus an introduction, and includes a poster in the back of the book. Each chapter is on a
