I need to know the link in Fe(OH)2?

Question

Fe = 8 electrons
O= 6
H=1
THANKSSSSSSSSSS!!!!!!!

I need the bonds between them. and how does it happen since Fe already have 8 electons..THANKS

Answer 1

Ok, so Fe has 8 electrons. OH has a total of 7 but there two OH molecules so that makes 14. 14 plus 8 is 22. So the whole molecule has a total of 22 elcetrons. First write Fe in the middle. Next draw a line on either side of it and write one OH atom on the end of these lines. Now, fill in all the orbitals with electrons (the lines you drew off of the Fe represent bonds between the Fe and each of the OH; each line is 2 electrons each). Filling the orbitals means putting 6 more electrons on Fe (two above and two below make it the neateat) and putting 3 pairs of electrons on each of the OHs. Now, I know this means Fe technically has 10 electrons, but in this molecule it is ok. Fe is one of the few elements that can do this. Some teachers also prefer for you to draw the molecule bent, meaning if you put the extra electrons on the top of the Fe, draw the two lines going to the OHs down a little bit, at an angle, not straight out to the sides.

It should look like this: (obviously the electrons on the bottom would be flush with the OHs but I can't make it that way on here.

Hope this helps! Good Luck!

Answer 2

can you clarify your question please?
do you mean what holds it together, it should be ionic bonds
