Electronegativity of Atoms We Should Know About

Postby Jasmine 2C » Fri Dec 06, 2019 3:42 pm

Can someone give a hierarchy of the electronegativities of main elements we should know about? Like I know F is the most electronegative and then O (I think?). And then there's C and S that are very similar? I would try to search up periodic tables of them but most give varying values. And I understand the trend is increasing from lower left to upper right but there are some edge cases that make it hard to determine.

I think you would be fine just to memorize the general trend...The specific values are relatively not important for the exam.

It is probably best to memorize the periodic trends that electronegativity has. As you go up the table EN increases, and as you go right from the table EN increases. I don't believe we will have to know the exact hierarchy/numbers for electronegativity, we just need to be able to work with the idea of EN based off of an elements position on the periodic table relative to another.

The trend is that electronegativity increases as we move across the period and decreases as we move down the group.

Knowing the trend of increasing electronegativity as you move to the right and to the top of the periodic table will be beneficial for what the questions will ask you.
