Metals have metallic bonds.
Fe and Co
non polar
FeCl3 Ionic Fe(3+) and three Cl(-)
Some examples are: Mn, Fe, Co, Ni, Cu. .
As measured by Slater, yes, as calculated by Clementi, no. Please see the link.
I think it is covalent
Fe and Co
non polar
FeCl is a metal (Fe) and a nonmetal (Cl), which means that it is a ionic bond.
Iron would form ionic bonds with sulfur.
Fe 2+andSO4 2-form the ionic bond,Ferrous sulfate, FeSO4, also know as iron II sulfate.
FeCl3 Ionic Fe(3+) and three Cl(-)
In this case the roman numerals indicate the oxidation state of the cation portion of the polyatomic ion: [Fe(II)O2]2- as opposed to [Fe(III)O2]1- Mn(II)=Mn2+ Mn(VII)=Mn7+
Some examples are: Mn, Fe, Co, Ni, Cu. .
Fe 2+and2Cl -Make FeCl2An ionic compound.
Mn(7+) is reduced to Mn(2+) going from purple to colourless/pale pink. The Fe(2+) ions are oxidised to Fe(3+) ions to complete the redox reaction.
Schists can have Mn and Fe, limestone has Ca and Mg in it while granitic rocks have K, Ca, Mg and fe.
