Periodic Chemistry (Ghana Only)


Welcome to the comprehensive course material on Periodic Chemistry, tailored for candidates in Ghana seeking to delve into the intricate world of Chemistry. This course aims to provide an in-depth understanding of the periodic trends in elements, focusing specifically on the physical and chemical properties of period 3 elements and their compounds.

One of the key objectives of this course is to unravel the mysteries of the periodic table, where elements are organized based on their atomic number and electron configuration. By studying the periodic trends, students will be able to identify the similarities and differences in the properties of elements across periods and groups.

As we embark on this journey, it is essential to explore the physical and chemical properties of period 3 elements such as sodium, magnesium, and aluminum. These elements exhibit unique characteristics that set them apart from elements in other periods, making them pivotal in understanding the trends in the periodic table.

Furthermore, students will delve into the fascinating world of complex compounds and bonding. By analyzing the bonding in complex compounds, individuals will gain insights into how atoms come together to form molecules with distinct properties. Understanding the shapes of complex compounds is vital in predicting their reactivity and interactions with other substances.

Moreover, this course will provide a comprehensive overview of the elements of the first transition series. Transition metals play a crucial role in various chemical reactions and industrial processes, making it imperative to grasp their properties and applications.

Throughout the course, students will be encouraged to engage with theoretical concepts and practical examples to deepen their understanding of Periodic Chemistry. By the end of this course, candidates will not only be able to identify trends in the periodic table but also analyze complex compounds, their bonding, and the properties of transition elements.
