Chemistry Lesson Note For SS2 (First Term)
Below are the 2022 complete Chemistry lesson notes for SS2 First Term
Week 1 – Periodic law
Overview – Dmitri Mendeleev, a Russian chemist in 1869 was the first to construct the periodic table. This periodic table is an arrangement of the elements by using their properties. Mendeleev used a specific pattern to place the elements into the table and the elements that had not been discovered in his time, he predicted them and their properties. According to the modern periodic law, the properties of the elements are a periodic function of their atomic number. This week, we shall learn about how the periodic table came about, the electronic configuration as well as the arrangement of elements into groups and periods. To learn more, Click here…
Week 2 – Periodic table and atomic properties
Overview – The elements of the periodic table follow a particular pattern called the periodic trends. The periodic trends refer to specific patterns that exist in the periodic table in the properties of chemical elements which explains certain aspects of elements and variations in their properties with increasing atomic number. This week, we shall learn about the atomic properties. We know that elements in the periodic table are arranged vertically in groups (0 – 7), we shall become knowledgeable about the properties of the groups. To learn more, Click here…
Week 3 – Oxidation–Reduction reaction
Overview – Abbreviated to Redox reactions, oxidation and reduction reactions are chemical reactions that involve two reactions that are different but still complementary. This week, we shall learn about the definition of oxidation and reduction reactions as well as how to identify a redox reaction. We shall become familiar with the terms reducing and oxidizing agents and how to balance redox reactions. To learn more, Click here…

Week 4 – Identifying oxidizing and reducing agents
Overview – Oxidizing and reducing agents are both chemical species involved in oxidation-reduction reactions. While an oxidizing agent is reduced and accepts electrons, a reducing agent donates electrons and is oxidized in a chemical reaction. This week, we shall how to identify oxidizing and reducing agents in chemical reactions. We shall also learn how to balance complex redox equations in acidic and alkaline media.

Week 5 – Ionic theory
Overview – Formulated by Arrhenius in 1887, the ionic theory helps to explain the process of electrolysis. According to the law, some molecules of electrolytes when dissolved in water will dissociate into freely moving charged particles called ions. This theory was later modified because of findings from X-rays diffraction studies. This week, we shall learn about the ionic theory. We shall also learn about the terms covalent and electrovalent bonds, electrovalent and covalent compounds, electrolytes and non-electrolytes, weak and strong electrolytes as well as conductors.

Week 6 – Electrolysis
Overview – Electrolysis is a process in which direct electric current passes through the solution of a compound or the molten state of that compound to bring about chemical decomposition. To help us understand the concept of electrolysis, we shall be introduced to some basic terminologies used in electrolysis. This week, we shall learn about electrolysis, its mechanism, factors that affect the preferential discharge of electrolysis and Arrhenius theory of electrolytic dissociation. To learn more, Click here…
Week 7 – Electrolysis of specified electrolytes
Overview – Having already been introduced to the concept of electrolysis, this week, we shall how the process of electrolysis occurs. We shall learn about the electrolytic process of specified electrolytes – molten sodium chloride, copper (II) tetraoxosulphate (VI) solution, brine and acidified water. It is important to always remember the factors that preferential discharge of electrolysis. We shall learn about the electrolytic cell and the uses of electrolysis. To learn more, Click here…
Week 8 – Electrochemical cells
Overview – Electrochemical cells are devices that produce electrical energy due to the occurrence of chemical reactions in them or they can make use of supplied electrical energy to run the chemical reactions that take place in them. These cells are of two types – Galvanic/Voltaic cells and electrolytic cells. This week, we shall learn about electrochemical cells and their differences. We shall also learn about the electrode potential and cell potential. To learn more, Click here…
Week 9 – Application of electrochemical cells
Overview – Electrochemical cells like we learnt in the previous week are used for the production of energy. This week, we shall learn about the applications of electrochemical cells and some examples of the electrochemical cells. We shall learn about the primary cells and secondary cells. Primary cells are galvanic cells that generate electrical energy through irreversible chemical reactions and secondary cells are rechargeable batteries that generate electrical energy through reversible reaction that occurs in the cell.

Week 10 – Faraday’s law of electrolysis and calculations
Overview – At this point of the term, we have gained reasonable knowledge about electrolysis. Electrolysis did not just bring up from nothing, a man called Michael Faraday, an English scientist who is considered to be the father of electricity propounded the laws of electrolysis. Faraday formulated two laws of electrolysis. This week, we shall learn about Faraday’s laws of electrolysis and how to solve problems on the laws. To learn more, Click here…
Week 11 – Revision
Overview – This week, there will be a revision on all the topics covered this term, from the periodic table and Faraday’s laws of electrolysis. We shall recall all we have learnt and use them to answer questions.
Week 12 – Examination
Overview – This week, we shall be examined on all we have learnt this term.
Week 13 – Examination
Overview – This week, we shall be examined on all we have learnt this term.
