Learn about valence electrons and how to find the number of valence electrons on the periodic table. Discover the role of a valence electron in an...
Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through ...
Sodium easily loses an electron because it belongs to group \({\rm{1}}\,\left( {\rm{A}} \right)\) of the periodic table. It has only one valence electron present in the outermost shell, which it readily loses to attain the stable noble gas electronic configuration of Neon \(\,\lef...

Since the energies of the shells are comparable, an electron of 4s makes a jump to 3d to fulfill a stable configuration. The number of valence electrons is now 1! A number of elements among the transition elements exhibit this oddity, which is also observed on the inner transition elemen...

Electronegativity (in terms of average valence electron energy) qualifies as the third dimension of the periodic table. The purpose of this paper is to effectively address this concept in fundamental chemical education in relation to the periodicity and properties of the elements....
