    Hmmm my parents always woke me up way too early I got ready and waited for them to do their stuff last minute (though for important things they usually planned ahead a little more) we were often late and it was my fault for not being ready (having my shoes on 10 minutes before we leave).

    Parents are clearly just hypocrites.






  • The table that does it that way is a complete mess but I guess it was a good idea and got some things right.

    They first started doing it with valence shells in 1864, Mendeleev had a pretty close one based on atomic weights in 1871 and correctly predicted that there were missing elements based on valences + weights. The atomic numbers which determine the valences appear to have been discovered about 40 years later.

    I guess you are correct but I think the question was about the modern table.







  • I’ve never heard anyone say either of those things but I don’t have an argument against the first one based my understanding of gender.

    I think that parts of your statement are likely correct but I doubt a lot of it. The comment you replied to was correct though it is likely more nuanced. That is where your point could play in (which is what enables much exaggeration used by opponents) but your examples show me that you are quite biased (not that I am not) and not necessarily part of those who would be willing to listen to the whole thing.



  • 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.
