ionization energy vs electron affinity

[dk00]

9 . If an atom's valence electrons are tightly held then we can
expect a
A) high ionization energy and a high electron affinity .
B) low ionization energy and a high electron affinity .
C) high ionization energy and a low electron affinity .
D) low ionization energy and a low electron affinity .


i thought it was A because it is hard to remove an electron if it is tightly bound and has a high affinity but the answer is apparently C with the explanation of "9- so is hard to remove (high IE) and easy to add (low EA)"
well if its easy to add wouldnt the affinity be high???

I agree. It seems like the answer would be A because if it's easier to add than it must have a greater electron affinity..

Ok thanks! So the "low electron affinity" could mean a very negative value? What if the value is largely negative? Isn't it playing with words at this point?

 

[Ezoption]

Yeah. Very negative and largely negative is one in the same in my eyes.

 

[dk00]

And low electron affinity is talking in terms of a value?
How am I supposed to know this, the electron affinity is in fact high but the value is negative how do we know if they are talking in terms of value or not

I guess it'll depend on how they word the questions. If they use the words high/low you can assume its talking about the values. If they use the words greater/smaller, stronger/weaker you can assume it's talking about it explicitly.
