This comprehensive unit builds upon basic chemical principles by exploring advanced concepts including atomic structure, bonding, periodicity through Period 3 elements, and the three main branches of physical chemistry: kinetics, energetics, and equilibrium. You will develop practical skills through mole calculations, examine the impact of green chemistry on industry, and master the fundamentals of organic chemistry including nomenclature, isomerism, and reaction mechanisms. The unit is structured progressively, with foundational knowledge at the beginning supporting more complex topics as you advance toward your final assessment, ultimately preparing you for higher education and careers in chemistry or related scientific fields. 

This unit explores three key areas: electromagnetic waves and their role in communication systems like mobile phones, Wi-Fi, and Bluetooth; the laws of motion that have led to crucial safety innovations including seat belts, airbags, and crumple zones; and electrical circuits with their relationship to energy usage and sustainable alternatives. Through studying physical principles, conducting practical investigations, and developing mathematical skills, you will gain insight into how everyday technologies function and contribute to environmental sustainability, while building the foundation necessary for progression to higher education and professional careers in nursing, healthcare, medical technology, dentistry, and laboratory sciences.
