Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

Alex Brown Heather Surface Writing Seminar 2 September 2013 Why People Attend College Let’s go back to the 1960’s. In the 60’s nobody went to college. Education past high school was unheard of.

Obvious sadness is often portrayed in America following watershed moments in United States history‚ like the abolition of slavery and the Great Depression. For example‚ symptoms

Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point

* Chemical Formulas and Reactions . . . Midterm Objectives: * To balance chemical equations. * To interpret chemical reactions. * To understand equilibrium reactions and the factors that can affect them. * Molecular Mass / Formula Mass * Is the sum of the atomic masses of all the atoms present in one molecule of that compound. Example: the molecular mass of sodium bromide‚ NaBr‚ is 103‚ which represents the sum of the atomic mass of sodium (23) plus that of bromide (80)

grudges for the one who want to give the knowledge will stop you from getting it; so keep the grudges aside and get the knowledge. It’s the best thing you can do. INTEREST This is the major reason why you READ READ READ and still don’t understand; INTEREST! Your interest towards the course makes it easier to understand. If you like science fiction and you are studying mass communication then it a total waste of time. So stick to your ball!!! GOOD LUCK AS WE ALL PREPARE FOR EXAMS Watch out

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility
