If you are a Class 11 (HSSC-I) FBISE student, these handwritten notes for Chemistry Chapter 10: Periodic Table are prepared according to the new FBISE National Curriculum 2022–2023. You can download the notes from the link provided under the Download section at the end of this post.
These notes explain the structure of the periodic table and trends in elemental properties in a simple and conceptual way, helping students understand how elements behave chemically and physically.
Chapter Overview: Periodic Table
The periodic table is one of the most important tools in chemistry. It arranges elements in such a way that their properties show regular patterns, known as periodicity.
Understanding this chapter helps students predict the properties, reactivity, and chemical behavior of elements without memorizing individual facts.
Topics Covered
The following topics are covered according to the FBISE syllabus Periodic Table and Periodic Law, Periods, Groups, and Blocks of Elements, Classification of Elements (Metals, Non-metals, Metalloids), Characteristic Properties of Elements in a Group, Chemical Periodicity, Trends in Metallic and Non-metallic Behavior, Reactions of Chlorides, Ionization Energy. Each topic is explained clearly with important definitions and trends for exam preparation.
Important Concept Explanations
Periodic Law: According to the modern periodic law, the physical and chemical properties of elements are a periodic function of their atomic numbers.
Periodicity of Properties: Properties such as atomic size, ionization energy, and metallic character change regularly across periods and down groups. These trends help in understanding element behavior.
Ionization Energy: Ionization energy is the energy required to remove an electron from an isolated gaseous atom. It increases across a period and decreases down a group due to changes in atomic size and shielding effect.
Why These Notes Are Helpful
These notes help students with Understanding periodic trends easily, Learning classification of elements, Preparing for MCQs, short questions, and theory questions and Conceptual clarity instead of memorization. The notes are written in a student-friendly format, making them ideal for quick revision before exams.

Final Tip for the Students
Instead of memorizing properties of elements, focus on understanding periodic trends. Once trends are clear, many exam questions become easy and logical.
