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.
Rushwr
  • Rushwr
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?
anonymous
  • anonymous
I'm sorry I'm horrible at chem my teacher gives me quizes and doesn't explain anything
Rushwr
  • Rushwr
it is the tendency of an atom to attract a bonding pair of electrons
anonymous
  • anonymous
Okay, so how would I figure this out?

OH i read your question wrong I didnt catch the ectronegativity chart @Rushwr i am sorry!
Rushwr
  • Rushwr
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
Rushwr
  • Rushwr
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
Zale101
  • Zale101
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|
Zale101

Electrongetivity increases to the right, and upwards of the periodic table

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
diamondboy
  • diamondboy
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
diamondboy
  • diamondboy
Do u know how to calculate polarity?
anonymous
  • anonymous
Not really
diamondboy
  • diamondboy
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:
diamondboy
  • diamondboy
|dw:1442602097290:dw|
anonymous
  • anonymous
Hmmm I'm still kind of confused
anonymous
  • anonymous
But I lost that question any way can you help with this one?

diamondboy
  • diamondboy
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
anonymous
  • anonymous
ve?
diamondboy
  • diamondboy
-ve means negative and +ve means positive
diamondboy
  • diamondboy
the answer to ur question is between option C and D
diamondboy
  • diamondboy
do u know ur answer now?
anonymous
  • anonymous
C? :D
diamondboy
  • diamondboy
Fluorine is more electronegative and so it should have the -ve charge
anonymous
  • anonymous
So D?
diamondboy
  • diamondboy
yep
diamondboy
  • diamondboy
hows dat? did it work?
anonymous
  • anonymous
And this is my last one but I have to leave or I'll be late getting my friends brother can you tell me and when I'm back on explain why? and it was right
