Chemistry Reflection Essay

For chemistry I had a good start because I remembered most concepts but there was this one big thing that during the review I totally forgot how to do it which was reading a periodic table. I know that's a very bad thing to not remember since everything in chemistry revolves around the periodic table and not understand it would make everything else seem more confusing than it has to be. I needed to work on chemical reaction types, half life, and titrations because they were the hardest and confusing concepts that I learned for this unit. Chemical reactions are confusing for me because I do not understand how to figure out what the reaction is even though I knew what the types of reaction are and there definitions but I couldn't figure it out.

Concepts that I felt like I did good on were balancing equations, nuclear reactions, electronegativity, and nuclear chemistry. Balancing equations was one concept I already knew how to do because my science 9 teacher taught this so it was not that difficult for me. But when you showed us the algebraic method I was so lost and confused because I never seen that before and it looked very complicated and hard. But my goal is to understand it because it is supposed to be easier and faster than the other way we were taught. I will do this by watching videos on khan academy about the algebraic method because they explain things well and they give you practice questions with helps a lot. Nuclear reactions made sense to me because it was not too complicated and the way it works is not that difficult to understand. The two nuclear reactions are nuclear fission and fusion the difference between them is that fusion is fussing atoms together to form a larger element and during this process it releases energy, also nuclear fusion is seen in

So when you look at a period table the more down the row an element is the more shells it has, if it is closer to the right side of the periodic table and the other element is on the left and same row than the element on the right is more electroneg, and finally the more charges an element has the more electroneg it is. Also by seeing how many electrons and protons are because if there are more protons than its more electroneg since the proteins are holding onto all the electrons. Nuclear chemistry is related to how alpha particles, beta particles, and gamma rays work. They were easy to understand and to solve for, and you can see that from the worksheets I did on nuclear chemistry. It's mainly just understand how the particles and rays work and there unit. For example, alpha particles are related to He because it has 4 as its atomic mass and 2 as its atomic number is the same as alpha. Batas unit is related to electrons because its atomic mass is 0 and its atomic number is
