![]() ![]() The melting and boiling points of alkali metals are shown below: Similarly, their melting and boiling points decrease down the group due to an increase in size. The s-block elements have low melting and boiling points due to their large sizes. Some most important minerals of s-block elements are: The electronic configuration of alkaline earth metals is shown below:Īlmost all the s-block elements are present in combined states. The electronic configuration of alkali metals is shown below: The s-block elements lose their electrons to form mono-positive and di-positive ions. While the alkaline earth metals contain two electrons. The alkali metals in the s-block contain one electron in their valence shell. Properties of s-block elements Electronic configurationĮach s-block element has valence electrons in the s-orbital. Each row of the periodic table contains two s-block elements. The s-block elements are on the left side of the periodic table except for helium. The elements of group IIA are called alkaline earth metals.The elements of group IA except hydrogen are called alkali metals.The s-block of the periodic table comprises the IA and IIA group metals along with hydrogen (H) and helium (He). s-block, p-block, d-block, and f-block is given below: s-Block of Periodic table f-block is characterized by Lanthanide and Actinide metals.Ī detailed discussion about four blocks of the periodic table i.e. ![]() d-block is characterized by metals with variable (transition) oxidation states.p-block is characterized by metals, non-metals, and metalloids of groups 3 to 8.s-block is characterized by highly electropositive metals along with helium and hydrogen.The divisions into the blocks are characterized by their distinctive nature. The term block was used by Charles Janet for the first time when he introduced his left step periodic table (LSPT). These are s, p, d, and f block elements that constitute the whole periodic table. The periodic table is divided into four blocks depending on the type of shells being filled.
