How do electronegativity values change across a row of representative elements?
1 Answer
As we face the Periodic Table, from LEFT to RIGHT....
Explanation:
Why? Well
On the other hand, we know that electronegativity DECREASES down a Group of the Periodic Table...and again this is reasonable, given that as we descend a column of the Periodic Table we remove the valence shell of ELECTRONS from the positively-charged nuclear core, and thus electronegativity DECREASES...
And so as physical scientists, as chemists, we should look at some actual data....
I hope you can see the numbers...because I cannot...
