Answer 1

here is the lab. the mess up is on the table on the top of the page. we wrote down the wrong numbers and read the tools wrong. please someone help

Answer 2

@Euler271 come help when/if you can please

Answer 3

i think your best bet is to use a site like this and count the lines:

http://web.physik.rwth-aachen.de/~harm/aixphysik/atom/discharge/index1.html

Answer 4

thanks will do. also one more question:

explain why the actual electron configurations for some elements differ from those assigned using the aufbau principle

Answer 5

i don't know but i literally copy/pasted the question into google and got results.

it appears that aufbau's principle is not reliable for atoms with atomic number larger than 40. hund's rule must always be taken into consideration

Answer 6

okay thanks @Euler271
and real quick on the lab do you know any of the conclusion questions? if not thats okay

Answer 7

i don't really.

but these are extremely common and re-used lab questions.

i started googling the first one and it auto-completed it pretty early lol. let me know if there is one you can't find ^_^
