Branches of Science, Elements and Compounds | General Awareness & Knowledge - Bank Exams PDF Download

Introduction

Science is a vast field of study that helps us understand the natural world and its fundamental principles. It is divided into various branches, each focusing on a specific area of knowledge. The Branches of Science include disciplines such as Physics, Chemistry, Biology, and specialized fields like Genetics, Ecology, and Astronomy, all of which contribute to advancements in technology, medicine, and industry.

Understanding the Elements and Compounds is essential to the study of Chemistry, as they form the basis of all matter. Elements are pure substances consisting of only one type of atom, while compounds are formed when two or more elements chemically combine. The periodic table organizes elements based on their atomic numbers, and each element has unique properties that define its behavior in chemical reactions. Compounds, on the other hand, have distinct compositions and play crucial roles in various natural and industrial processes.

This chapter explores different branches of science, the classification and properties of elements, and the significance of chemical compounds in daily life. By understanding these fundamental concepts, we gain insights into how the universe operates at both macroscopic and microscopic levels.
