1. Conquering the Periodic Table: Your Map to Elemental Properties
The periodic table is your ultimate guide to understanding the elements, the building blocks of all matter. It’s not just a pretty chart on the wall; it holds a wealth of information about elements’ properties, reactivities, and how they interact with each other. JAMB loves to test your understanding of the periodic table, so make sure you’re familiar with:
- Groups and Periods: The periodic table is organized into horizontal rows (periods) and vertical columns (groups). Elements within the same group share similar properties due to their electron configurations. Periods, on the other hand, show a progression of properties as you move across the table.
- Periodic Trends: As you navigate the periodic table, you’ll observe trends in properties like atomic radius, ionization energy, and electronegativity. Understanding these trends will allow you to predict the behavior of elements you might not have encountered yet.
For example, metals tend to be located on the left side of the periodic table and are generally good conductors of heat and electricity.
On the other hand, non-metals are typically found on the right and are poor conductors.
By understanding this trend, you can predict that an unknown element positioned closer to the left side on the periodic table would likely exhibit more metallic properties.

2. Stoichiometry: The Art of Balancing Equations
Ever wondered how much of one reactant you need to completely use up another in a chemical reaction? That’s where stoichiometry comes in! This essential concept deals with the quantitative relationships between reactants and products in a balanced chemical equation. JAMB frequently tests your ability to:
- Balance Chemical Equations: A balanced equation ensures there are equal numbers of atoms of each element on both the reactant and product sides. Mastering balancing is crucial for solving stoichiometric problems.
- Perform Mole Calculations: The mole is a unit that bridges the gap between the microscopic world of atoms and molecules and the macroscopic world we can measure in grams. You’ll need to convert between moles and grams to determine quantities involved in a reaction.
- Solve for Quantities in Reactions: Stoichiometry allows you to calculate the amount of product formed or reactant required given a specific amount of another reactant. Imagine you have 10 grams of sugar (C₁₂H₂₂O₁₁) and want to know how much water (H₂O) is produced during complete combustion. Stoichiometry equips you to tackle this problem!

5. Gaseous Behavior: Understanding the Laws that Govern Gases
Gases are a vital state of matter with unique properties. JAMB frequently tests your knowledge of gas laws, which describe the relationships between pressure, volume, temperature, and the quantity of gas particles. Mastering these laws empowers you to solve problems involving:
- Boyle’s Law: This law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. In simpler terms, if you compress a gas (decrease its volume), its pressure will increase proportionally.
- Charles’ Law: This law states that at constant pressure, the volume of a gas is directly proportional to its temperature. As a gas heats up, its particles move faster and spread out, occupying a larger volume.
- The Ideal Gas Law: This law combines Boyle’s Law and Charles’ Law, providing a combined equation to relate pressure, volume, temperature, and the amount of gas (measured in moles).
Imagine a scenario on the JAMB exam where you’re given the initial volume and pressure of a gas sample and asked to calculate its final volume after a change in temperature. By applying the ideal gas law, you can solve for the unknown volume.
That’s not all, there are more repeated topics in JAMB Chemistry Exam every year.

- Atomic Number and Mass Number: The atomic number (Z) represents the number of protons in an atom’s nucleus, which defines the element’s identity. The mass number (A) is the sum of protons and neutrons in the nucleus.
- Isotopes: Atoms of the same element can have varying numbers of neutrons, resulting in isotopes. Isotopes may have slightly different properties due to the change in mass.
- Electron Configuration: Electrons occupy specific energy levels or orbitals around the nucleus. Understanding electron configuration is crucial, as it dictates an atom’s chemical behavior and bonding tendencies.
JAMB might present you with problems involving calculating atomic numbers, mass numbers, or predicting the electron configuration of an element. A solid understanding of atomic structure equips you to tackle these challenges effectively.

7. Oxidation-Reduction Reactions: The Transfer of Electrons
Many chemical reactions involve the transfer of electrons between atoms. These are called oxidation-reduction (redox) reactions. JAMB often assesses your ability to:
- Differentiate Between Oxidation and Reduction: Oxidation is the loss of electrons, while reduction is the gain of electrons. In a redox reaction, one species undergoes oxidation while another undergoes reduction.
- Balance Redox Reactions: Balancing redox reactions requires ensuring the total number of electrons lost (oxidation) equals the total number of electrons gained (reduction).
- Assign Oxidation Numbers: Oxidation numbers represent the hypothetical charge an atom would have if all its bonding electrons belonged to the more electronegative atom. Assigning oxidation numbers is a crucial step in balancing redox reactions.
Imagine a JAMB question where you’re presented with an unbalanced redox reaction. By understanding the concepts of oxidation, reduction, and oxidation number assignment, you’ll be able to balance the equation and decipher the electron transfer process.
