Question

different between covalency and electrovalency

Answer 1

1)the number of electrons that an atom can shared to get stable electronic configuration is called covalency
2)the presence of unpaired electron causes it
3)the bond formed is covalent in nature.
Ex:in order to get stable neon gas configuration carbon shares its four valence electrons. thus it's covalency is 4
electrocovalency:
1)the number of electrons lost or gained by an atom to get stable electronic configuration is called as electrocovalency
2)inert pair effect and the energy difference between the next and (n-1)d subshells causes it
3)the bond formed is ionic in nature.
Ex:in getting neon gas configuration sodium lossess one electron chlorine

Answer 2

)The number of electrons that an atom can shared to get stable electronic configuration is called itcovalency. ... (a)The number of electrons lost or gained by an atom to get stable electronic configuration. (b) Inert pair effect and the energydifferences between the ns and (n-1)d subshells causes it.
