Observation of Different Photons when Elements are Heated Introduction: The bright line spectrum is the range of colorful lights that are emitted from an atom in its excited state. A “normal” atom‚ or an atom in its ground state‚ is when all of the atom’s electrons are in their proper energy level. When an atom is in its excited state‚ electrons jump to different energy levels making them unstable. As the electron tries to get back to its respective energy level‚ energy is emitted in the form

Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).

IGSCE Chemistry Notes Oxides Oxides are used to determine whether an element is a metal or a non-metal. Most non-metals are classed as acidic oxides. While most metals are classed as basicoxides. Acidic Oxides * Reacts with water to form acids * Neutralises alkaline solution to form salt + water Basic Oxides * Neutralises acidic solutions to form salt + water Amphoeteric Oxides * These are non-metals which display both acidic and basic properties Alkaline Oxides * Reacts
