For each of the following sets of elements, identify the element expected to be most electronegative and the atom expected to be least electronegative. a. K, Cr, Br b. Mg, Ra, Ca c. Cl, Na, Al

Figure A Figure B a. Which figure demonstrates repulsion? Which figure demonstrates attraction? b. Which of the two would have the smallest ionization energy? Use your answer from part a to explain. Figure C Figure D c. Now that there is another electron between the nucleus and the outermost electron in Figure D, will the outermost electron be easier or harder to remove than the outermost electron in Figure C?

Areas af partial negative and partial positive charges happen when: ekctrons are completely removed from both atoms O ckctrons spend time oqually with cach atom O ckctrons spend mare time with the more ckctronegative atom O the dlectronegativity is sa big an ciectron is completely transferred

O ELECTRONIC STRUCTURE AND CHEMICA... Deciding whether a Lewis... Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure [O=C-H]* :0: : CIC CI: [¤¤-6: 0/5 Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: 0 No, it has the right number of valence electrons but doesn't satisfy the octet rule. 000 The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: 0 Alia V No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* X Ar If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example,…
