jihooncity101:

which atom will pull most strongly on it’s valence electrons, sodium or phosphorus? Use Bohr models above to explain your answer, key terms: attraction, effective nuclear charge, atomic radius

Vocaloid:

thoughts on this one? looking at the periodic table, sulfur and phosphorus are in the same period (row) which means there's no major difference in shielding. the main difference you need to consider: sulfur has one more proton than phosphorus. this will result in sulfur having a greater positive effective nuclear charge in the nucleus. if the nucleus is more positive, do you think it will pull more or less strongly on the valence electrons?

unknownnnnnn: Static at 2 A.M. My mind doesnu2019t knock. It rearranges the furniture at 2 a.m., asks me to notice every creak. I lie still like that might help, like silence is a language my thoughts forgot. They line up with receipts, proof of moments I replayed too many times to pretend they were accidents. Iu2019m fluent in overthinking itu2019s the only subject I never skipped. I can turn one sentence into a courtroom drama, cross-examine my tone, convict myself without witnesses. People call me u201cstrongu201d because I donu2019t spill. They donu2019t see the cup shaking in my hands, how much effort it takes to keep the surface calm. Confidence comes in phases. Some days it fits like skin. Some days itu2019s a costume I forget Iu2019m wearing until it starts to pinch. I laugh on cue. I answer u201cfineu201d with convincing timing. Iu2019ve learned where to pause, how long eye contact should last, how not to sound like a question when Iu2019m one. The past isnu2019t loud. It doesnu2019t need to be. It just clears its throat at the wrong moments, reminds me what I already survived and what might try again. But hereu2019s the part I donu2019t downplay I stay. Even when my thoughts argue in circles, even when doubt files appeals. I choose presence over perfection. Breath over escape. I donu2019t win every round, but I donu2019t forfeit myself either. I am not the static. I am the one listening, deciding what deserves a response and what can fade without taking my name with it.
