Chemistry

Senior Secondary School (SS1-SS3)
Summary

Sit back and cast your mind to thousands of years ago. 

Think of the early, primitive men who made clothing from an animal hide to cover their naked bodies, men who dried up animal hides to make parchment used for writing, others who tanned hides to make leather which was used to make belts and sandals, and the first men who made wine from grape!!!

What do they all have in common? 

They all utilized knowledge of different aspects of Chemistry! 

Chemistry is as old as man himself. 

The word Chemistry comes from alchemy, which referred to an earlier non-scientific set of practices that sought to understand the constituents of matter. 

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions. It studies their composition, structure, properties, behaviour, and the changes they undergo during a reaction with other substances. 

A course in Chemistry starts with the study of elementary particles, atoms, molecules, substances, and compounds of matter.  

It goes on to study the interactions, reactions and transformations between atoms, leading to the formation of chemical bonds. 

During such reactions, energy is evolved, thus,  energy and entropy forms a major part of chemistry. 

Chemistry is typically divided into several major sub-disciplines, such as; 

-Analytical Chemistry 

-Biochemistry 

-Inorganic Chemistry 

-Organic Chemistry 

-Physical Chemistry. 

Welcome and enjoy your ride through this exciting field of study, for the career opportunities are limitless and lucrative, as the chemical industry boast of a net annual sales of US $980.5 Billion with a profit margin of 10.3%.
