Homework Help: Chemistry

Posted by Mary on Tuesday, April 27, 2010 at 12:15am.

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?
