Chemistry Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances. Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. The history of chemistry can be traced to alchemy, which had been practiced for several millennia in various parts of the world. The current model of atomic structure is the quantum mechanical model. Traditional chemistry starts with the study of elementary particles, atoms, molecules, substances, metals, crystals and other aggregates of matter. This matter can be studied in solid, liquid, or gas states, in isolation or in combination. The reactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together. Such behaviors are studied in a chemistry laboratory. The chemistry laboratory stereotypically uses various forms of laboratory glassware. However, glassware is not central to chemistry, and a great deal of experimental chemistry is done without it. vocabulary definitions: properties: خواص, خصائص matter: مادة atoms: ذرات chemical bond: رابط كيميائي chemical compounds: مركبات كيميائية chemical reactions: التفاعلات الكيميائية the central science: العلم المركزي: الكيمياء bridge: جسر. بنى جسرا، ربط بين alchemy: الخيمياء هي ممارسة قديمة كان أصحابها يسعون الى تحويل المعادن الى ذهب intermolecular forces: قوى بين جزيئية هي قوى الجذب أو التنافر التي تعمل بين الجسيمات المجاورة (ذرات، جزيئات أو أيونات). هي ضعيفة بالمقارنة مع قوة الترابط داخل الجزيء، القوى التي تبقي الجزيئات معا millennia: ألاف السنين atomic structure: البنية الذرية quantum mechanical model: النموذج الميكانيكي الكمي elementary particles: الجسيمات الأولية aggregate: مجموع solid: صلب isolation: عزل, فصل combination: اتحاد, دمج, مزج interactions: تآثرات, تفاعلات rearrangement: إعادة ترتيب stereotypically: بشكل نمطي glassware: آنية زجاجية central to: مهم بالنسبة ل, مركزي, اساسي great deal: قدر كبير, الكثير من experimental: تجربي تعليم الانجليزية الدرس 05 علم الاحياء او البيولوجيا /watch/Y237-Pc2PAw27 صفحتنا على الفيسبوك https://www.facebook.com/lisanenglish/
