Single Bonds A single bond is when two electrons--one pair of electrons--are shared between two atoms. You may find it helpful to search within the site to see how similar or related subjects are covered. A molecule is polar if the shared electrons are equally shared. A Double bond is when two atoms share two pairs of electrons with each other.
Hydrogen has only 1 valence electron whereas Chlorine has 7 valence electrons. A Triple bond is when three pairs of electrons are shared between two atoms in a molecule.

Polar bonding with an unequal sharing of electrons. A Polar Covalent Bond is created when the shared electrons between atoms are not equally shared. As you can see from the picture below, Acetylene has a total of 2 Carbon atoms and 2 Hydrogen atoms.

Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds. The mechanism of enzymatic action Lewis acid definition In acid—base reaction: Example 1: Review Covalent Compounds. Match each atom or molecule with its corresponding letter s: Compression bond direction In chemical bonding: Written By: Since 8 electrons are needed for an octett, they share the electrons.

Phosphorus needs to gain 3 electrons to fullfill the Octet Rule. Both of these bonds are important in organic chemistry. You can make it easier for us to review and, hopefully, publish your contribution by keeping a few points in mind.Covalent Bonding Tutorial — Covalent vs. Ionic bonds, explained - Crash Chemistry Academy
Each hydrogen atom has one electron and needs two to complete its first energy level.
