Which of the following processes requires the largest input of energy? (LO 6.5) 
(a) 
(b) 
(c) 
(d)

Accepted Answer

Hey everyone, we're asked to determine the process that will require the greatest amount of energy. And it looks like we have to look at our ionization energy trends. As we've learned when we look at a periodic table as we move from left to right, our ionization energy will increase Now as we go down a group, our ionization energy will decrease. Now looking at our answer choices, it looks like a B, C and E are looking at our first ionization energy, which corresponds to removing the first valence electron from a neutral atom. Now, if we rank these based on the question between a B. E and C. A would require the least amount of energy followed by be followed by E. And lastly, C. But as we can see right here, option D is in our second ionization energy which refers to removing a second electron. So our answer here is actually going to be d since cesium will require a much larger energy to remove an electron from CCM plus one to form cesium plus two. Now, I hope that made sense. And let us know if you have any questions
