Question

if two different atoms are bonded together with a purely covalent bond, what can we say about the electronegativities of the two atoms?

Answer 1

They are the same.

Answer 2

Thanks

Answer 3

How do I give medals?

Answer 4

Nevermind

Answer 5

You dont give medals.....you give money :)

Answer 6

@oOkawaiiOo hehe, isn't that nice.

@H_HOFF Just for fun:

Even though covalent bond only supposedly happen between ones with similar electronegativity, it's generally observed in the lab and in chem literature that metal-nonmetals can exhibit covalent characteristics if the oxidation of the metal is high. For example titanium dioxide acts pretty much like it's bonded by covalent bond.

The reason why any bond is covalent is because you have similar electronegativity. A difference between 0-1.3 will do the trick. Reason why highly oxidized metals form something similar to a covalent bond is because they have lost so many electrons that they have so much more protons than the electron density, so they pull electron more effectively, thus it's like they have a higher "induced" electronegativity.
