Answer:
Where the greatest electron density is. And isn’t. Look at water. H-O-H.
The oxygen has more electrons, AND 2 lone pairs - the Hydrogens will be partially positive, and so such a way shows the polarity; am arrow with +-> on the Hydrogen area. The “point” will have a negative sign; usually these are drawn as “partially positive” & “partially negative”, but I can’t draw that. Sorry.
Explanation:
I think the answer is electron shell.
We have to get the formula of the complex formed between Fe³⁺ and ethylenediamine.
The formula of the complex is: [Fe(<em>en</em>)₃]³⁺, where, <em>en</em> is abbreviation of ethylenediamine.
Ethylenediamine (<em>en</em>) is a bidentate ligand as it contains two donating sites (-NH₂ groups). Three ethylenediamine co-ordinate to central metal ion, Fe³⁺ and forms [Fe(<em>en</em>)₃]³⁺ with a co-ordination number of six.
