Re: H-bonds [ENDORSED]
A hydrogen bond works with only Fluorine, Oxygen and Nitrogen. If we take a look at the period table and remember the trends for electronegativity we see that these 3 elements are among the most electronegative, in which fluorine has the highest electronegativity. Hydrogen has a + charge, so the att...

Re: edta
It is hexadentate, so this means it can form 6 bonds.

Re: Fe------ferrate? [ENDORSED]
For iron the Latin name is used and so it becomes ferrum. If the whole coordination compound is negative then we add the -ate suffix.

What is the structure of SCl4 called? Just means the structure has five element, but it has another one pair on its center atom. SCl4 is called sulfur tetrachloride, it has 5 areas of electron density so it is in the group of trigonal bipyramidal and it has the shape of seesaw. Due to the 1 lone pa...

Ok, cool. Thanks now it makes sense to me. I was confused before because I did not undertand the concept of net charge on a molecule.

Re: Coordinate covalent bond?
Imagine I have ammonia, NH3 and Boron trifluoride, BF3. Ammonia has a lone pair of electrons on the nitrogen atom, and boron in the boron trifluoride only has 6 electrons not filling its octet. So in this scenario when the two molecules react, what occurs is the nitrogen is found to donate both of i...

Difference between charge and formal charge [ENDORSED]
An Hydrogen ion is said to have a charge of 1+, however in other molecules Oxygen for instance which is said to have a 2- charge but in a SO4 molecule it has a 1- charge. So what is the difference between these two?

Why do orbitals beyond f- exist if there are no elements that can fill these shells up? A quick google search will show the g- and h- orbitals. How are scientist able to compute these without having directly observed them?
