Ans.Alkali metals have a single electron on their outer shell, while all the noble gases (the Group 8 elements in the periodic table including helium, neon, argon) have a full valence band with no unpaired electron to cause a reaction with other molecules[15]. ...

As the twentieth century approached, elements of similar properties were arranged in eight main vertical columns referred to as chemical families. The first such family, or Group I, is collectively termed the "alkali metals," commencing with lithium. The next column, Group II, is designated the ...
These belong to Group 2 (the one following with alkali metal group) in the periodic table, with all the alkaline metals lying in the s-block[3, 4]. Alkaline-Earth Metals on the Periodic Table List of Alkaline Earth Metal Elements
Metals/Nonmetals: Colors according to the metallic character of the elements (alkali, alkaline earth, metalloid, transition metal, other metal, or nonmetal). Advanced Tab The figure below shows theAdvancedtab of thePeriodic Table. For a detailed explanation of the buttons, seeQuery features. ...
Cause of Periodicity in the Modern Periodic Table The cause of periodicity in properties is the repetition of similar outer electronic configuration after certain regular intervals. For example, all the elements of group 1 i.e. alkali metals have a similar outer electronic configuration, ns1. Her...
Alkali metals form a part of the leftmost group, i.e. group 1 of the modern periodic table. It contains six elements, which are collaboratively called the Lithium family. These metals are highly reactive metals of the periodic table due to the presence of one electron in their outermost shel...
The colored areas of our table break up the elements into groups of alkali metals, alkaline earth metals, lanthanides and actinides, transition and post-transition metals, metalloids, nonmetals, halogens, and noble gases. We go in-depth on each of these groups in the questions below. ...

5. Metals: In the periodic table, metals are placed on the left-hand side. Group \({\text{1}}\) and \({\text{2}}\) are called alkali metals, and alkaline earth metals, respectively.6. Non-metals: The left side of the periodic table is occupied by non-metals.7. Metalloids: ...
