Chemistry Basics Quiz

Chemistry is considered the central science as it provides a foundation for understanding various scientific disciplines. For example, it explains aspects of plant growth in botany, the formation of igneous rocks in geology, and how medications work in pharmacology.

Chemistry occupies an intermediate position between physics and biology and studies the chemical elements that make up matter, compounds made of atoms, molecules, and ions, their composition, structure, properties, behavior, and changes during reactions.

Chemistry has evolved and now encompasses various areas of specialization or subdisciplines which continue to increase in number and interrelate to create further interdisciplinary fields of study.
