Class 8 General Science | Part 5 | ETEA Test Preparation | PST CT PET DM AT TT Qari | Periodic Table & Properties of Elements


Welcome to Knowledge Pills!
In this detailed video (Part 5 of our General Science series), we cover important MCQs from Class 8 Science focusing on the Periodic Table, Atomic Structure, Properties of Metals, Non-metals, and Metalloids — essential for ETEA education cadre exams like PST, CT, PET, DM, AT, TT, Qari and others.

This video is based on KPK textbook content and structured for concept clarity, exam relevance, and easy retention.

📚 Key Topics Covered in This Video:

1. Halogens (Group VIIA) and their reactivity


2. Noble Gases (Group 0 / Group VIIIA) and their stability


3. Alkali Metals & Alkaline Earth Metals – Properties and Reactivity


4. Atomic Numbers and Electron Configurations (Na, K, Mg, Ca, Cl, etc.)


5. Periods and Groups – How elements are arranged in the Periodic Table


6. 2n² Formula – Maximum electrons in shells (K, L, M, N)


7. Valence electrons and their role in grouping elements


8. Placement and group identification of common elements (Carbon, Magnesium, Fluorine, etc.)


9. Classification of elements: Metals, Non-metals, Metalloids


10. Physical Properties of Metals (e.g., malleability, ductility, density, conductivity)


11. Non-metals – Characteristics and examples


12. Metalloids – Definition and examples (Boron, Silicon, Germanium)


13. Density – Definition and examples (Copper, Water)


14. Thermal & Electrical Conductivity – Concepts and applications


15. Use of copper in electric wiring and purpose of plastic insulation


16. Aluminium – Properties, uses, and alloy advantages


17. Groups IA, IIA, and VIIA – Key characteristics and elements


18. Electron shell arrangement and valence shell identification


19. Periodic trends and how elements behave based on their shell/electron count


20. Revision-focused MCQs with correct answers and Urdu translations
