I don't know...
If the difference in electronegativities between the two atoms is 2.0, or greater, the bond is ionic.
Here the electronegativity is 2.34 so it's an ionic bond.
But then they have given us the electronegativity table and has asked us to determine the bond type using that right? So I thought she knew about the electronegativity.
The ability for one atom to bind to another?
I'm sorry I'm horrible at chem my teacher gives me quizes and doesn't explain anything
it is the tendency of an atom to attract a bonding pair of electrons
Okay, so how would I figure this out?
OH i read your question wrong I didnt catch the ectronegativity chart @Rushwr i am sorry!
they have given us the electronegativity of K and Cl Find the difference if it is greater than 2 they are considered as ionic bonds
got it ?
I'm trying to figure it out now one sec sorry my comp is being slow today
the difference was 2.34 so it is ionic? @Rushwr
Nonpolar covalent has an electronegtivity difference of 0.2 - 0.5. A polar covalent has an electronegtivity difference less than 1.6. Ionics have an electronegativity greater than 2.0. Yes, 2.34 is greater than 2, so it is ionic.
Lets say this is the periodic table|dw:1442591503283:dw|
Electrongetivity increases to the right, and upwards of the periodic table
Okay, one sec I'm pulling one up
Crap, they're all tiny and I can't see the elements ;-;
Bubs sorry I was distracted!!! Hold on !
Electronegativity is the ability of an element to pull electron density towards itself, so it causes polarity. Polarity is a difference in the electron density from one end of a molcule/bond to the other. So if you bond something with a high electronegativity to something with a low electronegativity, this big difference causes a partial positive charge on one atom, and a partial negative charge on the other, which is polarity. But similar electronegativities give bonds with little or no polarity.
That kind of helps but I'm still not sure what my answer would be..
@WhatEven..... sorry for coming up late I guess u are good now
what she is trying to say is that when a highly electronegative element bonds with a less electronegative element part of it becomes -ve and part +ve, this is polarity. What we need to do now is to find out which one of d options has the highest polarity value
Do u know how to calculate polarity?
ok so all u need to do is to take d value of d highly electronegative element and subtract the less electronegative element from it. An example is this:
Hmmm I'm still kind of confused
ok so because F is more electronegative, and hydrogen less electronegative the bond becomes partly -ve and partly +ve. The highly electronegative one has the -ve charge while the less electronegative one has the positive charge
-ve means negative and +ve means positive
the answer to ur question is between option C and D
do u know ur answer now?
Fluorine is more electronegative and so it should have the -ve charge
hows dat? did it work?
Thanks I'll be back in like 45 minutes or less
It was right btw (:
sorry whats btw?
by the way lol
ok thank u. :)
