I have the idea that because the second shell is filled from lithium to Ne, the shell doesn't get larger. But why does it get smaller? Does this perhaps have something to do with the charge in the nucleus that might somehow attract the electrons?

Loading...There are exactly 2 questions that I don't understand! Hex-2-enal has two stereoisomers. Draw the isomers and name the molecules. -Write down the reaction equation for the detection of hex-2-enal using Fehling's solution. I've tried to draw the stereoisomers here. Could you give me a tip on how to draw them?
What is this process called—physically and chemically? Is it ammonia?
I read that copper chloride forms when you dip two copper electrodes in salt water and connect them to a 9V battery. The electrodes started bubbling (well, the water around them, that is) and the water turned a strong green color… can I throw it away, or is it toxic? I wanted to build a…
Hey, I have to give a chemistry presentation on a metal halide. Is there a special section where I can write a lot about it? That would be super helpful 🙂 Thank you in advance
I managed A) and B). As far as I know, in A) you only have to take the square root of the solubility product (because KL=[Ba2+]*[SO4(2-)]) and in B) I'm not sure, but I think the concentration of BaSO4 must be the same result as for the ions in A) because of the stoichiometric ratio…
Here the last sentence should probably be the most helpful.
I’m not a chemist now, but I guess that particles with different charge in the atom attract, and the larger the charge, the greater the attraction to differently charged particles, and therefore the radius becomes smaller… This should probably change again in the next shell, the core will first become larger, and then changes its size from large to small…
I also found something in a Wiki article.
