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.
A hiatal hernia occurs when part of your stomach protrudes up through the diaphragm into the chest. The diaphragm is a sheet of muscle that helps you breathe by contracting, drawing air into the lungs. hernia occurs when an organ pushes through an opening in the muscle or tissue that holds it in place. For example, the intestines may break through a weakened area in the abdominal wall. Hernias are most common in the abdomen. However, they can also appear in the upper thigh, belly button, and groin regions.
