Modern Inorganic Chemistry
Thus the binary compounds having ionic bonding are most readily formed by the
elements of groups IA and IIA with oxygen (group VIA) and halogens (VIIA group)
elements. Electrovalency Electrovalency of an element is its combining ...

... the maximum covalency is equal to the number of half-filled orbitals only
because they do not have vacant orbitals in the valence shell. 5. VARIABLE
ELECTROVALENCY There are many elements which exhibit variable
electrovalency.

Types of Valency There are two types of valency : Electrovalency and Covalency.
If an element combines by the loss or gain of electrons to form electrovalent
compounds (or ionic compounds), its valency is known as electrovalency, and if
an ...

Variable Electrovalency The electrovalency of an element is equal to the number
of electrons lost or gained by its atom during the formation of ionic bond. The s-
block elements do not show variable valency, however, p-block elements (with ...

Introduction to Inorganic Chemistry
The concept of electrovalency can be extended to atoms in semi-polar molecules
. We saw in Chapter 5 that the charge distribution in the HF molecule is
approximately H0.5+F0.5−. Thus if, as for an ion, we set the electrovalency of an
atom in ...

elements have already been discussed in the previous section. Many elements
have incomplete outside shells. When two of these elements are mixed, they
react ...

Typical electrovalency is most commonly foundin compounds derived
fromelements situated inthe groups adjacentto the inert gases. Thus a sodium
atom (1s2,2s2,2p6,3s1) may lose the electron occupying the 3s orbital, giving a
sodium ion.

Rudiments of Chemistry
Elements can attain nearest inert gas electronic configuration either (i) by actual
electron transfer or (ii) by sharing electron pair or pairs between the combining
atoms. Electrovalency : The combination between a highly electropositive
element ...
