Learn something new every day, pursue interests and answer questions that always made you wonder! These elements are extra stable due to completely filled s-orbitals and half-filled p-configuration. The General electronic configuration of this block is – Group 1 elements – [Noble gas configuration] ns 1, where n = 2 to 7. In the s-block elements the last electron enters in the s-orbital. p-block contains six groups from the group-13 or IIIA to group-18 or zero. The 's' block elements 's' block elements, (except helium) are those in which the valence-shell is the 'ns' orbital and where the last electron enters into the 's' orbital of the outer element. General Properties of the Transition Elements (d-block) Electronic Configuration. Calcium, the s – block element preceding the first row of transition elements, has the electronic structure. They easily lose the loosely held electron and give M + ions thereby are the most electropositive metals. The general electron configuration of all alkaline earth metals is ns 2. 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. The general electronic configuration of s block elements is ns1&2. 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. 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. Like alkali metals, these are s-block elements, and have two electrons in the valence shell in s-orbital. Due to the transitivity of properties, the d-block elements are known as transition metals. Alkali(Group 1) and Alkaline earth metals (Group2) and Helium are all s-block elements. It starts from scandium (Z = 21) and goes up to zinc (Z = 30). These elements are also a known as "Alkaline Earth Metals". Since the electrons in the d orbital basically lie between s and p orbitals, they show a transition from properties of s to p. Ca is located in the second column of the s block. For example, the s sublevel can only hold two electrons, so the 1s is filled at helium (1s 2).The p sublevel can hold six electrons, the d sublevel can hold 10 electrons, and the f sublevel can hold 14 electrons. The (n-1) stands for inner shell and the d-orbitals may have one to ten electrons and the s-orbital of the outermost shell (n) may have one or two electrons. P-block Elements: P-block elements have the common electron configuration of [noble gas]ns 2 np 1-6. The first transition series involves the filling of 3d orbitals. The general outer electronic configuration of such elements is either ns 1 or ns 2. But, helium has 1s 2 configuration; it is a special situation. These elements constitute one of the two series of inner transition elements or f-block. The d block elements electronic configuration in the fourth series can be given below. However, zinc, cadmium and mercury are considered along with d- block elements. We would expect that its electron configuration should end with s 2. First = [Ar]4s 2 3d x; second = [Kr]5s 2 4d x; For third and fourth transition series, the general electronic configuration isns 2 (n − 2)f 14 (n − 1)d x.
