Electronegativity

Postby 605379296 » Wed Nov 13, 2019 8:41 pm

Are we given an electronegativity chart for Test 2 to compare electronegativity difference?

I don't think we'll be given a chart. However, based on periodic trends, you should be able to figure out the relative electronegativity difference. Just remember that electronegativity increases as you go up and right on the periodic table.

Another way to remember it is that electronegativity follows the general increasing trend of ionization energy on the periodic table. That is except for the part in ionization energy where O is less than N. This dip in Ionization Energy is not present in Electronegativity.

Electronegativity is actually one of the more consistent periodic trends and generally increases across a period and decreases down a group. While a similar trend characterizes the ionization energies, do note (as mentioned above) that there is no decrease in electronegativity from N to O and from Be to B as there are for the IE's.

Usually anything on the far left compared to the far right (fluorine) of the periodic table will have the highest EN difference.

I don't think we will be receiving a chart but learning and using the periodic table trends of electronegativity will definitely help you out!

You can use the periodic trends to find which atoms are more electronegative.

In case we aren't given it, it is best to know the trends from the periodic table. As we are given the Periodic table, just draw the trends directly on there for easy access.
