This question asks you to identify how periodic trends change as you look at the elements in the periodic table. In the questions below enter the LETTER that corresponds to the correct picture in the figure. Note there is a small difference between the trends of electron affinity and electro negativity. Look at the text to see the difference between F and Cl. The solid blue area in picture B and the solid yellow area in picture E mean "the trends do not apply to this area". Which picture shows the periodic trends of metallic character? Which picture shows the periodic trends of ionization potential? Which picture shows the periodic trends of atomic size? Which picture shows the periodic trends of electro negativity? Which picture shows the periodic trends of electron affinity? Which picture shows the periodic trends of nuclear size?

Explanation / Answer

area of equilateral triangle= sqrt3a^2/3

area=root(3)*(0.08)^2/4=2.77*10^-3
so
WI to II= 2.77*10^-3*0.25*1.3-(-2.77*10^-3*0.25*1.3)
=1.8005mJ
