non polar covalent bond, is when the electronegativity of both the atoms in the molecule is similar/ equal, therefore each atoms pull on the electrons in the covalent bond is roughly the same, therefore the molecule/ covalent bond is said to be non-polar, therefore there is a symmetrical distribution of charge.

In the molecule H. 2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Thus, covalent bonding does not necessarily require that the two atoms be of the same elements, only that they be of comparable electronegativity.

A covalent bond means that there is sharing of electrons going on. the most common example would be between HH. A non covalent bond means that there is no sharing going on. One element looses an electron and the other one gains it.

The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds – in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH3, molecule the three N−H bonds have only a slight polarity (toward the more electronegative nitrogen atom).

A double bond between two given atoms consists of one σ and one π bond, and a triple bond is one σ and two π bonds. Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond. Two atoms with equal electronegativity will make nonpolar covalent bonds such as H–H. An unequal relationship creates a polar covalent bond such as with H−Cl.

Not all atoms attract electrons with the same force. The amount of pull an atom exerts on its electrons is called its electronegativity. Atoms with high electronegativities – such as fluorine, oxygen and nitrogen – exert a greater pull on electrons than atoms with lower electronegativities.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

The terms polar and nonpolar are usually applied to covalent bonds, that is, bonds where the polarity is not complete. To determine the polarity of a covalent bond using numerical means, the difference between the electronegativity of the atoms is used.

Valence electrons = the ones that can DO stuff. So a covalent bond = co meaning more than one and shared and valent meaning valence electrons. The outer electrons of two atoms get jiggy with eachother and form a covalent bond! Ta da! Now: you have electronegativity.

Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points.
