Question

Group 1A element sodium combines with Group 7A element chlorine to form sodium chloride or table salt. Based on this information, which expression is true about the electronegativity values of these two elements?
Na > Cl
Na < Cl
Na = Cl
We cannot make a prediction with the data provided.

Answer 1

i need help with this

Answer 3

Hey @BrycePinkerton !!

What do you think it should be?

Answer 4

i think its Na=CI but im not positive

Answer 5

Ok, let's see what info is given in our question. they say that Na donates one electron which is then accepted by the chlorine atom. This means that chlorine has the capability to accept electron pairs while Na has the capability to donate one. So chlorines are sorta electron hogs and snatch electrons from sodium. Thus electronegativity which is basically the ability to attract electron pairs is greater for chlorine than sodium.

Answer 6

so CI is greater right??

Answer 7

Yes.

Answer 8

kk Thanks!!
