Anybody here good at chemistry? I'm having a heap of trouble with my homework. (and if it turns out to be a eally easy question, please don't make fun of me.

)

What's your question?

~*Emma*~ · 04-25-2005, 02:06 AM

The question is:

"Write down how many electrons there are in the outermost shell for each of the groups"

I'm pretty sure the groups are groups I-VIII (1-8) on the periodic table of elements.

I'd like to help,but wouldnt know the first thing about chemistry.A girlfriend of mine took the subject in highschool and never stopped bitching about how complicated it was.She was in tears most of the time,it was that bad!

To determine the number of electrons on the outermost shell, just look at the periodic table, LOL. They should give you the configuration. For example, the configuration for Ne is 2-8. The last number is the number of electrons on the outermost shell. Therefore, the answer is 8. Refer to the following periodic table:

http://www.nysedregents.org/testing/...empertable.pdf

Also note that the elements in Group 1 have 1 electron on the outermost shell. Group 2 has 2, group 13 has 3, group 14 has 4, and group 15 has 5, and so on so forth. Whatever the group number is, mode (%) that by 10.

As for the elements btwn 3-12, it alternates.

I'm doing all this from memory. I learned chemistry last year. Hope it helps, tho.

**** CHEMISTRY! **** IT ALL!!!!

get one of those wee little composition notebooks to take notes in (ie formulas for conversions) and label it "useless **** (aka the little black book)" like i did.

**** YEAHHHHHHH. God I hate chemistry. I mean, it can be cool and all just...not when I have to learn about it

It's been almost a decade since I took chemistry and believe me, thinking about it still makes me shudder.

Warm & Fuzzy · 04-25-2005, 05:05 PM

Oh, c'mon. Chemistry isn't THAT bad, LOL. PHYSICS is the worst!

MsOrange · 04-25-2005, 09:48 PM

not the kind you do in school

Thank you! Thank you! I'll be here all week! Don't forget to tip your waitress.

That's how I feel about it too. I'm taking it this year and I mean I used to like it... and then we started doing all that math **** with all the calculations and percentages and formulas and now I despise it!

I loved physics.

Thanks, I got it now.

It didn't have the configuration numbers on the sheet I had.

Also, if you're any good at maths, could you help me with this problem (me and my mum were trying to figure it out last night with trial and error

. LoL we're not that good at maths formulas

):

"The school play was attended by 550 people and the revenue from ticket sales was $4980. If each adult paid $12 and each student paid $8, find how many adults and students attended the play."

I have no idea how to do it.

Our teacher explains things really fast (mostly no explaining but just writting it on the board and expecting us to figure it out ourselves

) and he won't let us ask questions.

If anyone knows how to solve it, can they talk me through it but NOT tell me the answer? I want to figure it out myself.
