Huh? It's sorted by number of electrons/protons (atomic number) the mass is dependent on that and the number of neutrons.
The eight main groups are based on the number of electrons missing for the atom to reach a full valence shell. Once it is full (8th group, noble gasses) it starts a new Period (row). I'm not sure how the other groups are chosen (probably some quantum physics that I never had in chemistry class). After looking it up Wikipedia says it just keeps going that way.
Electronegativity describes how much it "wants" to attract negative charges and doesn't affect the order (Flourine has the highest and is in group 7). I think you may have confused it with ionization energy which would certainly match my understanding of the top half of the periodic table and probably does work for the lower half too now that I think about it.
The groups tend to have similar properties but that is not why they are sorted that way. Hydrogen for example is quite different from other elements in group one. The colours are probably better for finding common properties.
Have a look through the history section. The concept of periodicity substantially predates the quantisation of the atom. The modern table certainly considers atomic orbitals to be key, but the groups were absolutely created based on common properties.

When we started learning about past tense (primary school, probably 6th year, amazing teacher), the first thing we learned was a list of irregular verbs. We spent at least a week just memorizing them before the regular -d/-ed verbs were even mentioned. I'd like to think it was a deliberate choice, to condition us to consider irregular verbs first when using past tense.
That same teacher also taught us how to write and read the international phonetic alphabet. Again, she was amazing.
i wish i had that teacher at school. thankfully i had a pretty good teacher in an english course i did for a few years

You had Peggy Hill as a full time Spanish teacherβ½β½ She's supposed to be a substitute!
Peggy makes me so mad. She's exactly the sort of person who would correct her students incorrectly, and be smug about it too.

One day I'm going to frame a coloured drawing I still have from year one. The following event is also still ingrained in my mind: We had to colour in a picture with several animals, one of which was a small spotted reptile in a puddle of water. Clearly a salamander.
The teacher crossed it out in red pen and screamed that I am old enough to know lizards are green and there is no such thing as a black and yellow animal on this earth.

Average autism experience tbh
Absolutely not

It's just a greentext. It's fake.
Also gay.
Mostly it's a fetishization of being the minderstood smart kid with scenarios that aren't true but feel true.
Pretty fake. Pretty gay.
I don't really like the slur I've been using here, but authenticity requires it. Oi moi.
I got this in school, it happens. Or happened in the 90s.

School nearly managed to kill my curiosity.
Nooo you can't learn about this physics stuff, you haven't learned the math yet.
Yes, that's a great question, hold it until next school year.
No, I can't explain that, it's not part of the subject matter.

I had a kindergarten teacher try teaching syllables by clapping them out while saying the word:
ALL I GATOR! Alligator! ALL I GATOR! Three syllables.Tried correcting her, she just clapped and said gator again.
wrote last edited by [email protected]I saw someone do this in teaching program evaluation materials once. Except the teacher did it with the word brown and stretched it into three syllables.

ow uh n.I remember thinking to myself "America is doomed." Sometimes I still think about that teacher when I see people get tilted over dumb, made-up shit on social media and turn into reactionary morons around election time. Br

it happens with bad teachers, and "good" parents will take the students side when the teacher's being an idiot.

Sounds like you had lame ah teachers. Some of my would take the time to explain relevant future concepts

Little did they know nearly no one needs to wield a pen now, or for the last couple of decades
Yep. Computer guy now as a trade. I touch a pen maybe once every 90 days.

wrote last edited by [email protected]I literally had a teacher once "correct" me for saying the area of a circle is ΟrΒ² instead of Οrr. I was told "you're not wrong but that's for future classes". On another class, I had a teacher correct a short story by removing repeated words, whereas I used repetition for emphasis, but used a comma instead of ellipsis. Think "I saw it, saw the thing" instead of "I saw it... saw the thing". Both was in early elementary, no higher than 3rd grade.
So, believe it or not, things happen to other people even if they didn't happen to you.
The worst thing about calling this fake is that it's not even unbelievable, it's a perfectly possible and mundane thing that most likely happened to millions of children as they grew up, yet everything in the internet is fake, right? No one just happens to record people for no reason, no one's smart enough to make funny jokes in the spur of the moment and get a reaction from strangers.
EDIT: Added context.

I'm pretty sure a currently 4yo nephew of mine will suffer some sort of bullshit like that in the coming years. Little bud is already able to read big numbers like 368 (also in english no less!) and full words despite the preschool not teaching either.

What the actual fuck.
Seems like they had the same math teacher as Anon.

I had a similar experience with square roots, writing both the positive and negative answers. It's wild for a teacher to actively reject correct answers because "that's not what we learned today" (the negative answers, in my case).

I had one really good high school science teacher. He pushed the school to start a class with the curriculum of "what do y'all wanna learn." I have never cared more about learning than trying to wrap my head around special relativity and the constant speed of light, or building rube goldbergs on the lab tables in the back. Imagine: kids want to enjoy learning! Fucking WOW! (little bit of spite there at the end)

Did I write this fucking greentext and then forgot or something, because this exact same thing happened to me, except they took my yugioh cards, not pokemon csrds
If I didn't learn to shut the fuck up and keep my head down, it would have happened to me, too.

I had an 8th grade social studies teacher/football coach tell us black people had an extra bone in their leg and that's why they were so good at sports. He was pretty well liked teacher tbh, we watched Oliver Stones "JFK" in his class. During lectures he'd come around and sit on the front of his desk to seem more relatable. He ended up on the school board eventually.
dam, that teacher probably invented a new more racist theory of why the NBA is majority African American

Man... This sucks. I can't believe how many lemmings have had similar experiences. I'm just remembering one now where I was excited about math, went ahead in the curriculum to fractions, and answered everything in ratios. Instead of the teacher seeing the simple mistake, I just remember them being "wrong". How deflating.
Kids need connection before correction. I'm sort of glad my kid is glued to a screen doing adaptive math. It sucks in its own way, but better than unfeeling correction. Though, at least in my district, there's a big emphasis on empathy development so I think the teachers try to model that.
Are fractions not ratios?? I continue to be perplexed by the oddity of bad teachers' thinking

in case you still care: the periodic table is arranged primarily by the chemical properties of its elements (mainly electronegativity, i.e. how much energy it takes to add/remove an electron to/from the atom) and also by their mass.
I do friend, I ended up looking into a few years later/have other teachers explain it but I never had that spark about it again
