Modern Chemistry is a bodily technological and it's far the examiner of the homes of and interactions among depend and energy. In one in all a kind words, chemistry is a way to look at the homes, tendencies, and physical and chemical adjustments of remember Chemistry is a scientific discipline involving elements and compounds of atoms, molecules and ions: their composition, their structure, their properties, their behavior and the changes they undergo with a reaction during 'other substances. Within its framework, chemistry occupies an intermediate position between physics and biology. This is sometimes called the central science because it provides a basic level of understanding at the basic and applied scientific disciplines. For example, the chemistry aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ology), ground on the moon (astrophysics), how drugs work (pharmacology) and how to collect DNA evidence at a crime scene (forensics).The atomic structure of the current model is the quantum mechanical model. A study of traditional chemistry with elementary particles, atoms, molecules, substances, metals, crystals and other aggregates of matter. The material can be studied in solid state, liquids, gas and plasma, individually or in combination. The interactions, reactions and transformations studied in chemistry are most likely the result of interactions between atoms, leading to rearrangements of chemical bonds. Such behaviors are studied in a chemistry laboratory.
