I have to give a chemistry presentation on Tuesday, and part of it involves iron. While practicing, I was trying to "determine" other transition metal elements and realized that what I'm explaining doesn't really fit. My question: How do you create the shell models in the transition metal groups? Or rather, how can I explain that iron has 14 e- in the third shell?

Loading...What is the structural formula of 2-methylpropane? Please write it in the style shown above left (see image). I don't understand the notation in the top right. I need it because I want to calculate the reaction enthalpy during combustion of the substance.
Hey, could someone please explain to me what to do when extracting tangerine peel? Using a Soxhlet extractor. Thanks in advance :))
If the Greens are in charge, extending this "poison injection" of glyphosate makes no sense, when at the same time there is a colossal decline in insect populations and the last bird populations will collapse because they will simply starve to death. Why don't the Greens say anything against this massive intervention in the natural…
I can't think of a solution to part b) at the moment, I would really appreciate some help ð. Thank you in advance!
Good day, I have a question about balancing a reaction equation, but more with the relationship between them. Example: O2+2Mgââ>2MgO How do they relate to each other? 1:1? Because you could also say 2:2, or rather 3:2? Because of 1 oxygen and 2 magnesium? Help!
Where can I get it? How much copper sulfate should I take to induce vomiting? Should I dissolve it in water? Thanks in advance!!
The shell model works perfectly when one dissolves from the idea that the shells are gradually filled.
Iron has 2 electrons in the 4s lower shell and 6 electrons in the 3d lower shell. It’s only a layer in the shaft. Manganese can occur at a value of 7; iron is only 6 and zinc is only 2.
Iron has 14 electrons in the 3rd shell, of which 6 are playing, 8 not. You can only explain that as far as you understood, half of the tubers, because half of them don’t listen.
I did not understand the courage that I did not understand, but thank you

Still as ignorant as before. Despite the
