Tackling Chemistry

04 Jun Tackling Chemistry

Another major component of science tuition is Chemistry. It makes up a uniquely defined field of study. Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions. It focuses on their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

Chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology). It also covers how atmospheric ozone is formed and how environmental pollutants are degraded. The properties of the soil on the moon, how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics) all fall under chemistry studies.

Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, ionic bonds, hydrogen bonds, and Van der Waals force bonds. The word chemistry comes from alchemy, which referred to an earlier set of practices. This practice encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. An alchemist was called a ‘chemist’ in popular speech. Later, the suffix “-ry” was added to this to describe the art of the chemist.

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. They can also be studied in isolation or in combination. The interactions, reactions, and transformations that are studied in chemistry are usually the result of interactions between atoms. This leads to rearrangements of the chemical bonds which hold atoms together. Such behaviors are studied in a chemistry laboratory. The periodic table gives greater insight into the naturally existing elements that make up the universe.
