The electronegativities of it's two atoms are similar.
Almost equal, difference < 0.5
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.
Nitrogen will form a non polar bond to another nitrogen, a polar bond to other atoms with different electronegativity. In NH3 N is the most electronegative, in NF3 it is F that is the most electronegative.
In a polar covalent bond, they spend more time closer to the more electronegative atom. In a non polar bond the spend their time mainly between the atoms showing no "favouritism"
Polar covalent. C is more electronegative than Si.
A covalent bond is a bond where atoms share electrons. For water the structure is H-O-H. The electronegative difference between the H and O allows them to be polar covalent.
If the elecrtronegativity difference is greater that 1.7 it is an ionic bond. If it is lower that 1.7 but greater than 0 it is a polar covalent bond. If it is equal to 0 it is a pure covalent bond.
The meaning is a significant difference of electronegativity.

It is a non-polar covalent bond. O - C - O The oxygen atoms have a delta- charge, and the carbon a delta+ charge. Because the negative charges pull the electron cloud into different directions, it has no side which is more electronegative than the other. Therefore it is a non-polar covalent bond.
CI2 does not exist. Cl2 with a lowercase L is the correct formula for chlorine gas. This is a covalent bond. Two atoms of the same element will never form an ionic bond with one another.
A polar covalent bond is a covalent bond between atoms in which the electrons are shared unequally.
When atoms share two electrons it is called a covalent bond. A covalent bond consists of two types of bond a polar covalent bond and a non polar covalent bond.
