Electrochemistry bridges chemical reactions and electrical energy. This course examines the mechanics of electron transfer. You will study galvanic cells that generate power and electrolytic cells that consume it. The curriculum covers cell structure, standard notation, and the role of inert electrodes.

This science drives portable energy and industrial manufacturing. You apply these principles when working with batteries, fuel cells, and corrosion prevention. Industrial applications rely heavily on this knowledge for metal extraction, electroplating, and purifying elements like aluminium and copper. Mastering this connects theoretical chemistry to practical engineering.

You will learn to identify cell components and write precise cell notations. You will calculate standard cell potentials, determine reaction spontaneity using Gibbs free energy, and apply the Nernst equation to non-standard conditions. You will also use Faraday's laws to compute mass deposited, time taken, and current passed during electrolysis.

This course is built for undergraduate foundation students in chemistry and chemical engineering. It is also directly useful for recent secondary school leavers preparing for university admissions. Engineering and materials science students will find this material essential for understanding thermodynamics and electrical systems.

Radioactivity powers our world, from nuclear energy plants to cancer treatment centres. This course reveals the invisible forces inside atomic nuclei that drive these technologies. You will explore radioactive decay, nuclear reactions, and the principles that govern how unstable atoms transform over time.

This knowledge applies directly to medicine, energy production, and environmental science. Nuclear engineers use these principles to design safe reactors. Medical professionals apply radioisotopes for imaging and cancer therapy. Archaeologists rely on carbon dating to determine the age of ancient artifacts. Understanding radioactivity opens doors to careers in nuclear engineering, health physics, radiology, and industrial safety.

By the end of this course, you will describe radioactive disintegration and identify alpha, beta, and gamma radiation; calculate half-life and decay rates for practical problems; explain nuclear fission and fusion processes; balance nuclear equations accurately; and recognise the applications of radioisotopes in medicine and industry. These skills form the foundation for advanced study in nuclear chemistry and related fields.

This course targets undergraduate students in chemistry, physics, medicine, and engineering programmes. It suits secondary school leavers preparing for university entrance exams and professionals needing a refresher on nuclear concepts. Even if you do not specialise in science, this knowledge helps you understand radiation safety, medical procedures, and energy debates that affect daily life in Nigeria and beyond.
