- koolstof - valentie en elektronische configuratie
Het atoomnummer van koolstof is 6. De elektronische configuratie is 2, 4. Het vereist:
4 elektronen om de elektronische configuratie van inert gas te bereiken.
- allotropen in koolstof-diamant en grafiet (verschil in fysische en chemische eigenschappen)
-binding in koolstof (covalnetbinding)
• koolstof heeft 4 elektronen nodig om de elektronische configuratie van inert gas te bereiken. Maar koolstof kan dat niet
vormen een ionische binding
• Het zou vier elektronen kunnen winnen die C4-kation vormen. Maar het zou moeilijk zijn voor de
kern met zes protonen om tien elektronen vast te houden.
• Het zou vier elektronen kunnen verliezen en C4+-kationen kunnen vormen. Maar er is een grote hoeveelheid voor nodig
van energie om vier elektronen te verwijderen.
• Koolstof overwint dit probleem dus door zijn valentie-elektronen te delen
andere koolstofatomen of met atomen van andere elementen.
• De binding die ontstaat door het onderling delen van elektronenparen tussen twee atomen in a
molecuul staat bekend als covalente binding
- soorten bindingen die koolstof kan vormen (enkel, dubbel)
-Lewis-structuren met voorbeelden

Over
I am Megha, an experienced educator with a wealth of knowledge and a burning passion for teaching. With 16 years of teaching experience, I have honed my skills and expertise to become a mentor who is dedicated to nurturing young minds. Holding a Bachelor of Education (BEd) degree, I have delved into the intricacies of pedagogical techniques, ensuring an optimal learning environment for my students.
My proficiency in both English and Hindi enables me to effectively engage with a diverse range of learners, breaking language barriers and fostering inclusive communication. I seamlessly transition between these languages, ensuring clarity and comprehension for students from various linguistic backgrounds. By employing this linguistic dexterity, I strive to make the learning process accessible and enjoyable for all.
My expertise lies in teaching Chemistry to students in grades 9-12, as well as Science and Mathematics to students in grades 6-8. Through my deep understanding of these subjects, I ignite a sense of curiosity and exploration in my students. I go beyond textbooks, incorporating practical experiments and real-life applications to bring these subjects to life. By doing so, I aim to instill a genuine passion for learning and empower my students to embrace these subjects with enthusiasm.
One of my distinctive qualities as an educator is my result-oriented approach. I design comprehensive revision tests that are tailored to address the specific needs of my students, allowing them to consolidate their knowledge and assess their progress effectively. I provide detailed and constructive feedback, guiding my students on their academic journey and helping them identify areas for improvement. My focus is always on enabling my students to achieve their desired outcomes and realize their full potential.
I firmly believe in recognizing the unique learning styles and preferences of each student. By understanding their individual strengths and challenges, I adapt my teaching methods to cater to their specific needs. Through personalized attention, I foster an environment that encourages self-confidence and motivation, nurturing a sense of empowerment within my students. I firmly believe that every student has the capacity to overcome obstacles and achieve academic success.
As an educator, I am driven by the desire to make a positive impact on the lives of my students. I aim to ignite a lifelong love for learning and equip my students with the necessary skills to thrive academically and beyond. Witnessing their growth and witnessing their success is the most rewarding aspect of my profession, reinforcing my commitment to providing quality education.
In summary, my journey as an educator is characterized by dedication, expertise, and a strong commitment to delivering excellent results. With my qualifications and specialized knowledge in Chemistry, Science, and Mathematics, I am equipped to guide and inspire students in their academic pursuits. Through revision tests, personalized feedback, and a dynamic teaching style, I am dedicated to helping my students achieve their goals and become lifelong learners.
