You should have one unbonded pair of electrons left on the phosphorus. This pair is going to make the shape of the molecule slightly tetrahedral (like a pyramid) and will cause the over electron distribution to be off. Whenever a molecule is not symmetrical it has a dipole moment.
Osteoarthritis, Arthritis in Dogs. Osteoarthritis, also known as degenerative joint disease (DJD), is defined as the progressive and permanent long-term deterioration of the cartilage surrounding the joints.
DJD of the hip is a loss of cartilage, or lining, of the hip joint. The cartilage serves as a cushion and allows for smooth movement of the hip.

This condition can result in a reduced quality of life and less active lifestyle. There are different types of DJD that may cause hip pain.
