A molecular bond
A covalent bond is only polar if there is a difference in electronegativity between the two atoms. Since the two oxygen atoms in an O2 molecule are identical there is no such difference.
The bond between oxygen atoms is considered as covalent.
A polar covalent bond is a bond between two nonmetal atoms with different electronegativity's. Technically, only a bond between identical nonmetal atoms would be truly nonpolar, but in most cases a threshold is set for electronegativity difference to be considered polar.
A compound is formed from atoms. Covalent bond is weaker.
A covalent bond between two atoms will be nonpolar if the two atoms bonded are identical, or if the two atoms bonded are not identical but have very quantitatively similar electronegativities.
No, the bond is covalent, but as the atoms are identical, it is non-polar.
A covalent bond between two atoms of significantly different electronegativities will be a polar covalent bond because the atoms will not share the electrons equally.
Covalent. There is no electronegativity difference between two atoms of the same element.
A pure covalent bond is a type of bond between two atoms sharing electrons. All the electrons are shared equally between the atoms in a pure covalent bond.
Covalent bond is formed by the sharing of electrons between two atoms and it is this force of attraction that holds the atoms in covalent bond together.
