Diatomic molecules are molecules made of two atoms chemically bonded together. The atoms can be of the same element (homonuclear molecules), or of different elements (heteronuclear molecules). Familiar examples of diatomic molecules of elements are the five gaseous state diatomic elements: Cl 2, F 2 H 2, N 2 ,and O 2.onding in Diatomic Molecules. In homonuclear diatomic molecules, the bonding is covalent. Each atom in the molecule has equal electronegativity; electrons are shared equally between the two atoms. In heteronuclear diatomic molecules, the atoms differ in electronegativity; these molecules have polar covalent bonds.
In a hiatal hernia, the stomach pushes up through that opening and into your chest. A small hiatal hernia usually doesn't cause problems. You may never know you have one unless your doctor discovers it when checking for another condition. But a large hiatal hernia can allow food and acid to back up into your esophagus, leading to heartburn. Self-care measures or medications can usually relieve these symptoms. A very large hiatal hernia might require surgery.
There are generally two types of hiatal hernia: sliding hiatal hernias and fixed, or paraesophageal, hernias. Sliding hiatal hernia. This is the more common type of hiatal hernia. It occurs when your stomach and esophagus slide into and out of your chest through the hiatus. Sliding hernias tend to be small. They usually donât cause any symptoms. They may not require treatment. Fixed hiatal hernia. This type of hernia isnât as common.
