The shared valence electrons between two nonmetal atoms is called a covalent bond. Think about the term covalent. 'Co' means share and 'valent' refers to valence electrons. Two shared electrons are known as a single covalent bond.ovalent bonds are formed when two atoms begin sharing electrons. The electrons are attracted to the positively charged nuclei of the atoms. A dipole results when electrons in a covalent bond are not shared evenly between the two atoms.
Loose, white, sticky, greasy, foamy, floating, smelly stool appearing several hours after a fatty meal is called steatorrhea. Main causes of white diarrhea are: Acute or chronic pancreatitis (low appetite, pain in the middle or left upper abdomen, nausea) Pancreatic cancer (low appetite, weight loss).
People who develop a cancer or stone that blocks the common bile duct, which transports bile to the intestine, will notice pale or white stools. But don't panic if there's a sudden change in the colour of the stool. Darkly pigmented foods such as blueberries or beets can change the colour. Iron pills and the bismuth in Pepto-Bismol can also darken stools. The composition of stool is also dependent on the amount of fat consumed. Normal stool contains about one percent fat. Passing stools that contain seven percent fat creates a condition called steatorrhea. These stools are soft, smelly and stick to the sides of the toilet bowl. This problem if chronic, is due to a lack of enzymes produced by the pancreas, or it may be temporary due to an extremely fatty meal.
