The general electronic configuration of s block elements is ns1&2. The general characteristic electronic configuration may be written as (n – 1)d 1–10 ns 1–2. Alkali Metals [Group-I] Group-I elements have one electron in their valence shell. Electronic Configuration The general electronic configuration of transition elements is (n-1)d1-10ns1-2. Alkali metals and its respective salts have the capability to impart colour to the oxidizing flame due to the heat generated from the flame which excites the valence electrons from one energy level to another energy level. But, reducing ability (oxidation potential) depends on the combined energy difference of three processes: Lithium, being the smallest ion, its hydration enthalpy is very high than caesium and compensates more than its higher ionization enthalpy. %PDF-1.3 %���� A diagonal relationship in S block elements exists between adjacent elements which are located in the second and third period of the periodic table. So substances having lower reducing ability than them will not be able to reduce them. In the s-block elements the last electron enters in the s-orbital. In the S block elements, the density of the alkali metals increases down the group. S block elements are strong electropositive elements with low reduction potential indicating their strong reducing ability compared to others. &��R�%�5����z�+���I� ���� �>��5b�&�Y�n�\iׂ:�t��F+Kǒ�5�֍o'M)9�,�*�o�>���z'��B�x��)�tR����vzۅ���p�BV�NU�L�@�o�����>�v��Z������%m�q���Yg�q^�{��=S�-����0.vJ� ;����SCɋ:ӫ% x�ɼGDB�J�%���Ry��!>��)N�[�*Dm*�N)����̕�����n[q�;�/�rN��{\��%�=��m�\�Ajd�ն[o,5�����B�7/C3�=KуB�I�Eڰ�;��כnX�Aʙ�W��)J*&;�4�ᷚ`�u���(���('�A����8��y�o���΁�B�nyxYJ��w;�LFc��@ȶ�j�C��joF��&��y���m9�*5�n���JZ��J�ӺC���!
