Dr. Von introduces the study of atoms, their subatomic particles, and electron arrangement, then builds the periodic table to explain atomic structure and its role in chemistry.
Explore atomic structure and periodic table by examining atom components, electron configuration, isotopes, and how matter classification into solids, liquids, and gases shapes element properties.
Define the atom and explain atomic number, mass number, and isotopes; illustrate with carbon and hydrogen, noting protons, neutrons, electrons, and chemical symbols.
Explore how ionization energy measures the energy needed to remove an electron from an atom, considering electron shells, distance from the nucleus, and implications for chemical reactivity and bonds.
Explore how shielding effect and nuclear energy shape atomic structure, using hydrogen and helium to explain effective nuclear charge, ionization energy, and outer shell shielding.
Understand how the modern periodic table uses atomic number, radius, first ionization energy, electron affinity, and electronegativity to rank elements, with Fluorine highest and Francium lowest on the Pauling scale.
Welcome to this course on atomic structure and the periodic table. This course has been designed in alignment with the IGCSE curriculum, and comprehensive lectures have been prepared to cover all prescribed topics. Additionally, several videos have been included to bridge the knowledge gap between high school and A-level content.
Although the topics covered are tailored to the IGCSE curriculum, this course is also suitable for any student in grades 11 and 12.
If you find that any topic relevant to this level has not been included, please feel free to share your feedback in the discussion section. I will be glad to incorporate those topics into the course.
Should you encounter any challenges in applying concepts to problem-solving, I would be more than happy to address these difficulties in the videos and provide detailed explanations. Therefore, do not hesitate to post your questions or suggestions in the discussions.
Thank you for choosing to learn with me. I hope this course marks the beginning of an exciting and enriching scientific journey. I look forward to seeing you all soon.
