Ans 6 :
When two atoms make a bond by sharing of electrons , it is called as covalent bond. This covalent bond is formed between the elements that have comparable electronegativity values.
So here , the covalent bond formation is likely in :
a) two F atoms : covalent bond
b) a H atom and a S atom : covalent bond
c) two O atoms : covalent bond
d) an Al atom and a N atom : Not covalent bond
Add Answer to:

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
