MnO4-
« on: September 07, 2006, 08:00:09 AM »
I would like to ask which kind of bonding is form between MnO4-/(permanganate ion)

If it's covalent bond, why the metal can form it non-metal but not the ionic bond?

if it's ionic bond, then how to draw the diagram?

waiting for the answers :)!

Frankly, I can't understand what you mean.

I mean, metal forms ionic bond with non-metal.
And Mn is a metal, and O is non-metal. They should form ionic bond rather than covalent bond.

However why the answer is still the covalent bond???

Take a look at some of the major properties of manganese, such as electronegativity.
