Is there a greater answer for naming D-Block elements the way they do?

AI Thread Summary
The discussion centers on the use of shorthand notation in electron configurations, specifically for D-Block elements like manganese, which is represented as [Ar]4s2 3d5. This shorthand is not merely a convenience; it highlights the stability of non-valence electron configurations that remain consistent across higher elements. The practice allows chemists to simplify complex configurations while acknowledging the underlying stability of these electrons in the periodic table. This approach aids in understanding electron arrangements without losing sight of their significance in chemical behavior.

Ok so I’m going into my second year of college and I’m starting to learn more advanced chemistry (pray for me🙏) I’m currently on the topic of D-Block elements and I was already aware of electron configurations and how to write them out… however what I have never come across prior was the use of another elements electron configuration to almost ‘shorten’ writing out one for example the electron configuration of manganese is [Ar]4s2 3d5 (embarrassing if I wrote it wrong but please correct me if I did) I had a general question, is there a deeper meaning behind using another electron configuration in a configuration or is it just chemists taking a shorter route and almost being lazy lol😆 any experienced chemist please respond, I’m a baby chemist trying to learn!! Thank you a million.😁

In a way - both. Yes, it is "just" a short notation, but it also reflects on the fact non-valence electron configurations are quite stable and identical in every "higher" element.

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
