RE: Chemistry Express: How Atoms Begin to Associate
Thanks again for the wonderful explanation. You nailed it again. Upvoted :)
Btw, nowadays, teachers start throwing concept of spdf right there. My younger bro was telling me that he learnt about protons and electrons in his physical science class, and their teacher said that this 'orbit' concept is not correct, they should learn the 'orbital' from the very beginning. I was highly surprised. Okay, maybe his teacher wants to tell the students everything, but students should actually get the basic idea before jumping into those stuff.
How we can exite an electron and make it jump from a lower exitation state to a higher exitation state, and their tendency to loose energy and come down... these concepts needs to be developed. You explained it well. :)
Thank you, @nirmal :) I agree that for kids, it can be really difficult to grasp the idea of a probability distribution without even knowing the basics of classical mechanics yet! I know that in most science classes kids get taught about the Bohr model first, which is a good basic approach. However, the concept of energy shells and valence electrons is the necessary basis for all the other things that come next in chemistry in my opinion. Electronegativity, periodic groups, bond types... even oxidation numbers etc. These are the "boring theory" for some, but it actually saves a lot of memorization and a lot of "why?!"s. Personally, when I started studying chemistry, electron configurations was the first thing I learned. It took me ages and a lot of effort, but after that, everything seemed to make sense :)
Hmm. You are correct. :)
