A covalent 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.ovalent bonding is implied in the Lewis structure by indicating electrons shared between atoms. The term covalence in regard to bonding was first used in 1919 by Irving Langmuir in a Journal of the American Chemical Society article entitled The Arrangement of Electrons in Atoms and Molecules.
Causes. Leg length discrepancies can be caused by poor alignment of the pelvis or simply because one leg is structurally longer than the other. Regardless of the reason, your body wants to be symmetrical and will do its best to compensate for the length difference.
Correcting your shorter leg length. When one leg is shorter than the other, you may be dealing with either an anatomical leg-length discrepancy (a permanent leg length deficit) or a functional leg-length discrepancy (temporary). Nearly all cases that come before us are permanent.f you do have one leg shorter than the other, it is recommended that you rectify your problem right away. If left untreated, the following are just some of the problems you are quite possibly could experience: 1  Bending of the spine. 2  Ligament damage. 3  Serious muscle pain. 4  Slipped spinal discs. 5  Swelling of joints.
