Which of the following elements (C, B, Be, Li for both parts of the question) will have the greatest increase in ionization energy between the removal of the first and second electrons? Which has the largest atomic radius?

a. beryllium,boron
b. boron, lithium
c. beryllium, carbon
d. lithium, boron
e. carbon, boron
f. lithium, lithium
g. carbon, lithium
h. boron, boron

Okay. So, ion energy increases to the right(for each step, s,p, etc) and decreases down the periodic table. Atomic rad increases to the left and down the table.

That means Li is the biggest, and C has the greatest increase? The answer being G in that case. Is this correct?

you have to keep in mind its asking for the greatest increase ionization energy when the between the removal of the first and second electron. That is basically saying it will lose 1 electron no problem but the second one would be a lot harder. therefore you would have to look to see which column willingly loses one electron but not two. so you would be looking for an akilli metal. atomic radius you were right about. your answer would be f for the reason i stated above

Yes, you are correct. The element with the greatest increase in ionization energy between the removal of the first and second electrons is carbon (C), and the element with the largest atomic radius is lithium (Li). Therefore, option G, "carbon, lithium," is the correct answer.

Yes, you are correct! To determine which element has the greatest increase in ionization energy between the removal of the first and second electrons, you need to consider the trend of ionization energy across the periodic table. Ionization energy generally increases from left to right within a period and decreases from top to bottom within a group.

To answer the first part of the question, you can compare the elements beryllium (Be), boron (B), lithium (Li), and carbon (C). Starting with Beryllium and moving from left to right, the ionization energy generally increases. Therefore, beryllium has a smaller increase in ionization energy compared to boron, which is located to its right. On the other hand, carbon, which is still further to the right, has a greater increase in ionization energy compared to boron. So, c. beryllium, carbon is the correct answer.

For the second part of the question, you need to determine which element has the largest atomic radius. In general, atomic radius increases from right to left within a period and increases from top to bottom within a group. Among the four elements mentioned, lithium is located on the far left side of the periodic table, so it has the largest atomic radius. Therefore, lithium is the answer for the second part of the question.

Hence, the correct answer is g. carbon, lithium.
