Compound

A traumatic accident like a fall or car crash can break your leg or other bones in your body. If a broken bone pierces your skin, it’s called a compound fracture. You’ll need surgery to realign your bones and then a cast to keep them immobilized. Always go to the emergency department if you think you have a broken bone. Overview What is a compound fracture? A compound fracture is a break or crack in your bone that is visible through your skin. Generally, bones break as a result of force and/or trauma like a car crash. Fractures can also be caused by less traumatic but repeated force. For example, if a soldier frequently marches with a heavy pack on their back, the repeated force on their leg could cause a crack in their fibula. What makes a fracture “compound” or “open” is when the broken bone pierces your skin. If you happen to fall from a ladder and land on your arm, breaking it, you’ll know it’s a compound fracture if you can see the bone. “Simple” or “closed” fractures don’t break through your skin. Compound fractures are extremely painful. It may also be frightening to see your bone exposed. A fracture is a serious injury, and you should immediately go to the emergency department for help. Which bones can fracture? Any bone in your body can break, but compound fractures most commonly occur in your limbs (arms, hands, legs and feet). Less commonly broken bones include: • Ribs. • Collar bone. • Eye bones. • Pelvis. • Skull bones. • Face bones. • Spine or vertebrae. Symp...

Learning Objectives • To understand the differences between covalent and ionic bonding. The atoms in all substances that contain multiple atoms are held together by electrostatic interactions—interactions between electrically charged particles such as protons and electrons. Electrostatic attraction between oppositely charged species (positive and negative) results in a force that causes them to move toward each other, like the attraction between opposite poles of two magnets. In contrast, electrostatic repulsion between two species with the same charge (either both positive or both negative) results in a force that causes them to repel each other, as do the same poles of two magnets. Atoms form chemical compounds when the attractive electrostatic interactions between them are stronger than the repulsive interactions. Collectively, the attractive interactions between atoms are called chemical bonds. Chemical bonds are generally divided into two fundamentally different types: ionic and covalent. In reality, however, the bonds in most substances are neither purely ionic nor purely covalent, but lie on a spectrum between these extremes. Although purely ionic and purely covalent bonds represent extreme cases that are seldom encountered in any but very simple substances, a brief discussion of these two extremes helps explain why substances with different kinds of chemical bonds have very different properties. Ionic compounds consist of positively and negatively charged ions held...

Compounds: A compound is a pure substance similar to an element. However, it represents a combination of two or more elements that are chemically combined in a fixed mass ratio to form a new substance known as a molecule. That is why it is referred to as a chemical compound. Have you ever thought that table salt is a compound? Yes, table salt is nothing but a sodium chloride compound made up of sodium and chlorine elements combined chemically. To learn more about Compounds, read the below article. Define Compound A compound is a pure substance that is composed of atoms of two or more elements, bonded chemically with one another in a definite proportion. Hence, it can be broken down into simpler substances by only chemical means. The properties of compounds are different from the properties of their constituent elements. The smallest unit of the compound is known as a molecule. Hydrogen element forms maximum compounds in chemistry. For example, wateris represented by the chemical formula \(\) by mass. Other examples of compounds include salt, sugar, sand, carbon dioxide, washing soda, chalk, alcohol, etc. Table Showing Some Common Compounds, Elements Present in them and their Formula Sl.

These are organic compounds and inorganic compounds. • Inorganic Compounds: Inorganic compounds are those derived primarily from non-...

It is best for combining two or more sentences that are self-sufficient but related into a single, unified one. Compound sentences give your writing a faster pace and unite related ideas, but they have a few more rules than standard sentences. In this quick guide, we explain how to use them properly to give your writing an edge. Grammarly helps you communicate confidently Write ...

Compound verbs Compound verbs are two words which combine to make one meaning. The first word is usually a noun, an adjective or a preposition, and the second word is a verb. The words are sometimes written as one word and sometimes joined by hyphens. A good learner’s dictionary will tell you how the compound is normally written: … Compounding When we use compounding, we link together two or more bases to create a new word. Normally, the first item identifies a key feature of the second word. For example, the two bases back and ache can combine to form the compound noun backache, and the two bases post and card combine to form the compound noun postcard. …

Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail. A neutral hydrogen atom, shown left, contains one electron. Two hydrogen atoms can combine by donating each of their electrons into a single covalent bond, depicted on the right as the area where the gray clouds around each hydrogen atom overlap. In the covalent bond, the electron pair is shared between the two hydrogen atoms. When the covalent bond is formed, we no longer have two separate hydrogen atoms but instead a single molecule of hydrogen—H 2 _2 2 ​ start subscript, 2, end subscript .
