Electronic configuration of p block (group 15) elements : In group 5 elements, the valence shell electronic configuration is ns2np3. Due to the transitivity of properties, the d-block elements are known as transition metals. These elements are also a known as "Alkaline Earth Metals". Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. The General electronic configuration of this block is – Group 1 elements – [Noble gas configuration] ns 1, where n = 2 to 7. It starts from scandium (Z = 21) and goes up to zinc (Z = 30). These are known as alkaline earth metals. Electronic Configuration. Electronic Configuration of D-Block Elements: In the transition elements, d-orbitals of penultimate shell are successively filled. Since the electrons in the d orbital basically lie between s and p orbitals, they show a transition from properties of s to p. The general electronic configuration of the d-block elements is (n − 1)d 1–10 ns 0–2.Here "(noble gas)" is the configuration of the last noble gas preceding the atom in question, and n is the highest principal quantum number of an occupied orbital in that atom. On the basis of electronic configuration, the elements may be divided into four groups, that is s, p, d & f. This division is based on the name of orbital which receives the valence electron. The general electronic configuration of f-block elements is:: (n-2)f^1–14(n-1)d^0-1ns^2. s- Block elements: Elements in which the last electron enters the s- orbital or their respective outermost shells are called s- block elements. All the d-block elements are classified into four series which are called 3d, 4d, 5d and 6d series corresponding to the filled outer shells of 3d, 4d, 5d, and 6d orbitals. Alternatively, remember group 1 (alkali metals) and group 2 (alkaline earth metals) are s-block, groups 2 throuh 12 are the d-block, 13 to 18 are the p-block, and the two rows at the bottom of the table (the lanthanides and actinides) are f-block. However, the electronic configuration of all the tripositive ions (the most stable oxidation state of all lanthanoids) are of the form 4f n (n = 1 to 14 with increasing atomic number). Radium is a radioactive element. The d-block Elements (Transition Elements) These are the elements of group 3 to 12 in the center of the periodic table. For example, mercury is toxic and is threat to the environment. Helium is an s-element, but nearly always finds its place to the far right in group 18, above the p-element neon. As the s-orbital can accommodate only two electrons, two groups (1 and 2) belong to the s-block, The general electronic configuration of s-block elements is ns l or 2. Hence their electronic configuration may be represented as [noble gas] ns 2 where ‘n’ represents the valence shell. Comprehensive learning themes for ages 9-18.
