lovelyharmonics · Answer

It'd be magnesium right?

lovelyharmonics · Answer

Snce it's in the same group?....

thomaster · Answer

what's the effective nuclear charge of those 5 atoms at valence level?

lovelyharmonics · Answer

What .-.

thomaster · Answer

do you have any idea what effective nuclear charge is?

lovelyharmonics · Answer

Nope c: wouldn't it make sense that it'd be magnesium though?

thomaster · Answer

Nothing makes sense if you don't know the basics. Perhaps you'll understand it after reading this: http://dl.clackamas.cc.or.us/ch104-06/efffective_nuclear_charge.htm

.-. I'm in a pretext and we haven't learned any of this stuff yet .-. So the the answers oxygen right?

wait, im not entirely sure... @Kainui  got some time ?

lovelyharmonics · Answer

So groups are good, periods are bad. Simple enough c: thanks

kainui · Answer

Woah wait, that's all completely wrong I'm sorry.

kainui · Answer

Now I'm not even sure, I stayed up all night and I am not sure. It's either Lithium or Magnesium definitely. I just don't know now which is more significant here. I'm gonna have to head out sorry.
