Firstly Polar means an UNEQUAL distribution of electron density within a covalent bond.
This is because two atoms of DIFFERENT elements join with a covalent bond. However one atom maybe more electronegative than the other, this means the more electronegative atom has a 'stronger' ability to attract the electron pair within the covalent bond towards itself. So the electron 'cloud' surrouding the two atoms becomes distorted towards the more electronegative atom.
This causes the more electronegative atom to become Delta - and the atom with the lower electronegativity to take on a partially positive charge Delta + .
So the greater the difference in electronegativity between the two atoms the more polar the covalent bond is.

If two covalently bonded atoms are identical the bond is identified as?
If two covalently bonded atoms are identical, the bond is identified as a nonpolar covalent bond.
Is a covalent bond considered polar or nonpolar?
Both actually. It just depends on the electro-negativity of the atoms bonded together. If both have the same electro-negativity, it is a nonpolar covalent bond. Otherwise, you have a polar covalent bond.
What happens when a polar covalent bond and a nonpolar covalent substance combine?
When a polar covalent bond and a nonpolar covalent substance combine, they may form a heterogeneous mixture where the polar and nonpolar components do not mix together. The polar and nonpolar substances will tend to separate due to their differing intermolecular forces.
What is N-O bond type ionic polar covalent nonpolar covalent or metallic?
Polar covalent. Due to the difference in electronegativity between nitrogen (N) and oxygen (O), the bond they form is polar covalent, meaning that the electrons are not shared equally between the atoms.
What type of bond is ammonia?
The bonding in ammonia, NH3 is a nonpolar covalent bond.

Is HCN nonpolar covalent bond?
This molecule contains polar covalent bonds.
What type of bond is ammonia?
The bonding in ammonia, NH3 is a nonpolar covalent bond.
What are the two subtypes of covalent bond?
nonpolar bond and polar bond are the two subtypes of a covalent bond
Is O2 an example of a polar covalent bond or nonpolar covalent bond?
O2 is an example of a nonpolar covalent bond. In an O2 molecule, the oxygen atoms share electrons equally, resulting in a balanced distribution of charge and a nonpolar molecule.
When atoms in a covalent bond share electrons unequally the bond is said to be...?
nonpolar scano:)
Is there a polar bond in ch4?
C-H bond of it is polar.CH4 has four such bonds
Is a covalent bond considered polar if the two atoms share the electrons equally?
No, a covalent bond is considered nonpolar when the two atoms share the electrons equally. If the electrons are not shared equally and there is an unequal distribution of charge, then the bond is considered polar.
Is BF3 non polar covalent polar covalent or ionic bond?
BF3 has a nonpolar covalent bond because the electronegativity difference between boron and fluorine is not significant enough to create a polar covalent bond. In a nonpolar covalent bond, electrons are shared equally between the atoms involved.
