The oxidation state of elements in the p block is maximum when it is equal to a total number of valence electrons, that is, the sum of s and p electrons. Group 13 elements (B, Al, Ga, In, and Tl) have diverse physical and chemical properties. Boron is the only nonmetal in the ...
to Wade's rules, while EHMO calculations are useful for determining counts of higher nuclearity clusters.The three-dimensional networks usually have overall electron counts which are balanced by the total number of valence electrons in the structure, in which the alkali metals are completely ionized...
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 shell, called thevalence electron.

1 All of the atoms in alkali metals have one electron in their outer electron shells. To become stable they have to give off one electron to elements with seven electrons in their outer shell making it eight, also stable. Then they become single charged positive ions (cations). Melting ...
In 1982, a type of superalkalis with the formula MLk+1 (where k is the number of valence electrons needed to close the electronic shell of the electronegative atom M and L is an alkali metal atom) was identified [3]. Wu et al. [4] demonstrated the earliest experimental evidence of ...
