For A Groups (Representative Elements): For B Groups (Transition Elements) (s and pblocks) n = period number d blocks: n = period number­ 1 f blocks: n = period number­ 2 • The electronic configuration of an element can now be given if the position in the Periodic Table is known: In the modern periodic table, elements are in order of atomic number in periods and groups. 03.07 Electronic Configurations of Elements and the Periodic Table – II 3.07 Electronic Configurations of Elements and the Periodic Table - II. Therefore, the electronic configuration of sulfur can be written as 1s 2 2s 2 2p 6 3s 2 3p 4. The metal of Group 2 in the periodic table from top to bottom are Be, Mg, Ca, Sr, and Ba. 2020. Therefore, the lowest energy orbitals are filled first. The (n–1) remains for the inward d orbitals which may have one to ten electrons and the peripheral ns orbital may have one or two electrons. State the common feature in the electronic configuration of all these elements given. Table of Electron Configurations for the 1st 18 Elements ! Generally, the electronic configuration of these elements is (n-1) d 1–10 ns 1–2. Elements in the same group in the periodic table have similar electronic configurations. For example, the elements lithium , sodium, potassium , rubidium, cesium, and francium (the alkali metals of Group I) all have electronic configurations showing one electron in the outermost (most loosely bound) s … Hassium: Value is a guess based on periodic table trend. Hence, the outermost electronic configuration of the s block elements is ns 1 or ns 2 as all the inner orbitals are completely filled. The above table showed the 1 to 30 elements electronic configuration along with their respective atomic numbers of elements from 1 to 30. Electronic Configuration of copper (Z = 29): Expected configuration: 1s 2, 2s 2 2p 6, 3s 2 3p 6, 4s 2 3d 9. The picture above is the solution to all your electron configuration problems.
