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?

A) Na > Ci
B) Na < Ci
C) Na = Ci
D) We cannot make a prediction with data provided.

Answer 1

Hi!

What do you think it should be?

Answer 2

@Abhisar I have absolutely no idea. Maybe C? That's just a guess.

Answer 3

Within a periodic table elements belonging to group 1A are called as Alkali Metals and have least electronegativity while those in 7A are called as Halogens and have maximum electronegativity.

Answer 4

So there for its B

Answer 5

Right?

Answer 6

What do u think @alextable ?

Answer 7

I was thinking B, as well...

Answer 8

Thank you! :)@Abhisar
