Over the week, we've done many moodle quizzes and lots of class discussion about the Lewis structure including hypervalency. We also went over the polarity in the shape of our molecule. I find the polarity overall easy, basically if there's a lonely pair then it would "bent" the shape of the molecule due to the change in repulsion. There was also another note on the bond strength, length, and order. Basically, these laws are all based off from the Coulumb's law. As the length of two nuclei increases, the force of attraction decreases so the force of repulsion would be greater because the electrons of the atoms. Also, all of the elements in period 3 or greater can have more the eight electrons around the central atom because of the empty d orbital available for them. Specifically for Boron and Beryillum, the two special cases where boron can only have three covalent bond and beryllium can form two covalent bond.
I think all of the notes were easy to understand once I am used to what I am doing, but honestly I find the lecture videos extremely hard to interpret because there really that much step-by-step examples shown in the video. In the video, it talks a lot about the theories and laws using these fancy and complicated words, especially in an online setting where students can’t ask about their confusions of the video and everything goes in a really fast paste. So I find it difficult to understand the lecture videos sometimes whereas if the teacher discusses the notes in the classroom, students are able to have a chance to ask questions on the things that they don’t fully understood. This is also the reason why some of the moodle quizzes took me a while to finish and fully understood the material. I find the whiteboard discussions in class very interactive and helpful to my learning style.
Other than that, it's been a great week in fact. I still cannot believe we are halfway done with the trimester. I really need to pick up my grades though. I guess this is the reason why people say junior year is so stressful because all of the stuff just comes on you all at once. Where in one hand, you have all of these extra-curricular activities and the other hand, you have an extra amount of work and studying you have to do for school. Especially the fact that, I'm taking the ACT in less than two weeks puts me onto an enormous amount of stress. I am already lacking a lot of sleep and a little behind in some of my other classes with the fact that I have not yet started my studying for the ACT. I think I'll just have to see how it goes and practice a couple more times. I am really jealous now of the middle school life, no stress and no worry. It's all part of growing up.
