Elements and compounds are a result of the actions of the valence electrons. There are three types of bonds that I have learned about in the bonding comparison lab. These bonds include ionic‚ polar covalent‚ and non-polar covalent. Each of these bonds and the element compounds connected to them has individual solubility‚ conductivity‚ melting point‚ and volatility levels. The three element compounds that will follow are sodium chloride‚ sucrose‚ and p-dichlorobenzene. Sodium chloride is an ionic

*Compound Interest/Discount* Compound Interest When you borrow money from a bank‚ you pay interest. Interest is really a fee charged for borrowing the money‚ it is a percentage charged on the principle amount for a period of a year - usually. If you want to know how much interest you will earn on your investment or if you want to know how much you will pay above the cost of the principal amount on a loan or mortgage‚ you will need to understand how compound interest works. * Compound interest

metallic‚ ionic and covalent bonds. Metallic - A chemical bond in which electrons are shared over many nuclei and electronic conduction occurs. Ionic – A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. Covalent - A chemical bond that involves sharing a pair of electrons between atoms in a molecule. 2. Explain the structure of metals‚ ionic compounds‚ covalent molecules and covalent networks and give examples

Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

Covalent Bonding In a covalent bond‚ a pair of electrons is shared between two atoms. Each of the positively charged nuclei is attracted to the same negatively charged pair of electrons. The diagram: A and B are held together by this shared attraction. Covalent bonds are often drawn as dots and crosses diagrams to show that the electrons have come from two different atoms. Molecules have a certain fixed number of atoms in them joined together by covalent bonds. Examples: Bonding in hydrogen

Group# 2 Experiment No. 1 ------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The

The compound is the substance that can be two or more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if

University of Education Introduction According to Wikipedia‚ a compound is a lexeme (less precisely‚ a word) that consists of more than one stem. Compounding is the word formation that creates compound lexemes (the other word-formation process being derivation). It refers to the faculty and device of language to form new words by combining or putting together old words. In other words‚ compounding occurs when a person attaches two or more words together to make them one word. The meanings
