X D LQ A Z H|V R 5 E You will use the known periodic trends to compare properties for elements indicate with letters in this periodic table. Consider their relative positions for these questions. Your answers will be letters as indicated above, not the actual element symbol they would coordinate to. (Do not use a real periodic to answer this question.) • Which element would be expected to have the lowest first ionization energy? • Which labeled element in the fourth period of the chart above has the highest quantity electron affinity energy? N

Suppose you were trying to find a substitute for K+ for some application. Where would you begin your search? Which ions are most like K+? For each ion you propose, explain the ways in which it is similar to K+ and the ways it is different. Refer to periodic trends in your discussion.

Can you explain the Mg examples below on the slide? It is NOT an assignment; this is a slide from a professor lecture.

The graph below shows the first ionization energies for the elements of the second period. While the general trend is that ionization energy increases when going from left to right of the period, neither B nor O follow this trend. Explain why the first ionization energies for B and O are less than Be and N, respectively. 1st lonisation Energy for Perlod 2 2200 Ne 2000 1800 1600 1400 1200 1000 Be 800 600 Li 400 200 3 4 5 6 7 8 Atomic number 9 10 1st IE in kJ/mol

The first five ionization energies (IE, through IE) of a Period 2 element have the following pattern: kJ/mol IE₁ IE₂ IE3 IE4 IE5 Make a reasonable guess about which element this is. Enter its chemical symbol below. Ś

Which specific electrons are added/removed, in this order, to form the ion?

explain and give an answer for this please
