paramagnetic

an element (atom/ion) with at least 1 unpaired electron

diamagnetic

an element (atom/ion) with a completed subshell - aka no unpaired electrons

isoelectronic

describes elements with the same # electrons but different # protons - aka same electron configuration - example: Be+ and Li

coulombic attraction (what specifically makes it higher or lower)

higher # of protons means it’s higher, higher distance means it’s lower. remember distance typically has higher impact than protons because it’s squared

photoelectric effect/photoelectron spectroscopy

we dgaf how it actually works but it’s basically used to determine electron configuration. make sure yk how to read a graph.

how do iupac names work?

IF there’s a transition metal in the compound, write the ELEMENT and then its charge in roman numerals in parentheses

common naming: know for copper, lead, tin, iron

cuprous/cupric, plumbous/plumbic, stannous/stannic, ferrous/ferric

whats yawls favorite pokemon? just flip the card gawd

know hypochlorite, chlorite, chlorate, perchlorate AND this number of Os applies to every halogen w/ same pattern

bicarbonate/hydrogen carbonate

HCO₃^- also know that hydrogen carbonate is iupac

ammonium

NH₄⁺

acetate

CH₃COO^- ball secret is to write it this way so it’s easier to draw the diagram but yes C₂H₃O₂^- is fine too

hydroxide

OH^-

nitrate

NO₃^-

permanganate

MnO₄^-

chlorate

ClO₃^-

sulfate

SO₄^2-

carbonate

CO₃^2-

chromate

CrO₄^2-

dichromate

Cr₂O₇^2-

phosphate

PO₄^3-

if u dont know this the ates and ites will haunt you

ate is always the one with more oxygen than ite. also, ates and ites have the same charge if the element connected to the Os is the same and singular
