If electrons are shared unequally in a covalent bond, it is known as d. Non-polar covalent bond b. Metallic bond a. lonic bond c. Polar covalent bond
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...
Part A What is meant by the term polar covalent bond? O A polar covalent bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. A polar covalent bond is the attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group A polar covalent bond is a covalent bond in which electrons are shared unequally, being more attracted to...

Covalent bonds form between hydrogen, carbon, and oxygen atoms when valence electrons are shared between the atoms valence electrons are subsituted between the atoms electrons are attracted to the nucleus protons are shared between the atoms
