The periodic table of elements series#

Let’s see how they stand in the periodic table: Metals Metalloids are elements with mixed characteristics.The non-metals on the other hand are elements having negative ions.The lustrous or shiny elements that form naturally below the surface of the Earth are called Metals.Elements of this block are also called inner transition elements.Ĭheck the Development of the Periodic Table here.Electronic configuration of lanthanides is 6s25d0-24f1-14.The electronic configuration of actinides is irregular.

The periodic table of elements series#

The f-block consists of two series lanthanides and actinides of the periodic table.The three series of transition metals are known 3d series, 4d series and 5d series.This block contains the elements of groups 3 to 12 of the periodic table.Valence shell electronic configuration is (n-1)d1-10 ns1-2.In d-block elements, a valence electron enters in d-orbital.These elements are called transition elements.At the end of each period is a noble gas element with a closed valence shell ns2np6 configuration.In fact, the heaviest element in each p-block group is the most metallic in nature. The non-metallic character of elements decreases down the group.It is interesting to note that the non-metals and metalloids exist only in the p-block of the periodic table.The outer electronic configuration of these elements is ns2 np1.The p-Block Elements comprise those belonging to Group 13 to 18 and these together with the s-Block Elements are called the Representative Elements or Main Group Elements.The compounds of the s-block elements, with the exception of those of lithium.Because of high reactivity, they are never found pure in nature.These elements are soft metals, electropositive and form basic oxides.They are all reactive metals with low ionization enthalpies.The elements of Group 1 ( alkali metals) and Group 2 ( alkaline earth metals) which have ns1 and ns2 outermost electronic configuration belong to the s-Block Elements.In these elements, the valence electron enters an s-orbital.s-block, p-block, d-block, f-block Elementsĭepending upon the type of orbital receiving the valence electrons, the elements can be classified into four following blocks: Read more about the Position of Hydrogen in Periodic Table, here.
