-Someone smart

This class is actually one of the most interesting that I have ever taken. Discussions about quantum mechanics... String theory.. Newtons Laws and how they pretty much apply to "everything"
Facinating.

lol I had a test about all the elements this week.. and it was freaking borring.. but I did get a 10 (in dutch) think thats an A in english. just he highest possible. and I also like science and physics because we have a cool teacher.

unununium ftw!

a few of the synthetic elements can't be tested since they degrade too rapidly

raul, some of the metals don't have one at all; only like 5, though.

and yes, toad, I started this year

all elements do have a zero or greater affinity (well technically the noble gases haven't been tested).... what periodic table are you using? lol

hmmm... ok, so when, i think its like beryillium, had that greater than zero afinity, that means that to gain an electron it uses energy? my question is, why wouldnt all the elements have that greater than zero afinity, because they don't want to gain those electrons, its the longer path to being stable...
i can't remember the actual name of it... but is there something like ionization energy or something? the noble gases have the highest amount of energy, and then they go down, i think its like the opposite of electron afinity, (lose electrons maybe?)

alright, the reason the right side of the table has greater affinities is that as they gain additional electrons beyond their neutral state, they become more stable (approach a full valence level) so they release energy, the measure of the energy released is the affinity

or something to that effect, but it should get you close enough lol

ya thats what it is... but our teacher won't do anything until we can prove it all... i guess the more "negative energy" (im not sure if thats really what it is... but like halogens have -320, so thats what i mean to say) and the bigger that number is, the easier it? also some elements have greater than zero energy, so basically, they get really pissed if you take an electron away, cuz they have a full sublevel which i guess is fairly stable... but then my question is... why would we even bother learnign the electron affinity of all elements if some elements want a positive charge, why don't all elements before the (i think its) the boron family have all greater than zero energies... they want to lose their electrons, not gain them...

Also, should make this topic a place to ask anything about science? chemistry at least, so IMREALEZ here would be a place to put your 1337 fish question and fl00ds 1337 fish response anyways... there we go =/

Farn you just start chemistry as well?

and fl00d3d hates spam;

I just learned this myself, and if I remember correctly, Electron Affinity is how much energy it takes for the electron to form an ionic bond? If not, correct me lol

I thought i'd respond first to Raul w/ a new topic
so......im in first year of chemistry, so those long scientific posts will just hurt my brain but ya..
I guess this will prolly be updated cuz im going to learn more in class... but anyone wanna help me truly understand Ionic Energy(?) and Electron Affinity... i sorta got it, but then if i tried to explain it, i wouldn't really know how
