8-7 Why is the first ionization energy for phosphorous higher than the first ionization energy for sulfur even though the general trend in the periodic table is to have the ionization energy increase as you go from left to right on the table. 8-8 The three most common oxidation states for Fe are +2, +3 and +6 what are the most likely electronic configurations for these three ions? 8-9 Why do transition metals have magnetic properties? 8-10 Just looking at...
(2 pts) Why is the first ionization energy of oxygen smaller than the first ionization energy of nitrogen?
Considering the trends in ionization energies, would you expect sodium or potassium to be more reactive? Explain. Considering the trends in atomic radii, would you expect cesium or radon to have the larger radius? Explain. Compare the ionization energies of sodium and rubidium and then compare the electron affinities of chlorine and iodine. Which of the following chemical combinations of the elements would be the most exothermic - Na and Cl, Na and I, Rb and Cl, or Rb and...
the H2 molecules hydrogen gas have lower potential energy than the hydrogen molecules in water
100. Which of the following elements would you expect to have the lowest first ionization energy? a. F d. I b. Br e. Xe c. c1 - --
D Question 10 Why is Bra smaller atom than As? Br is actually larger than As because it has more protons. As is larger because it has more protons and electrons. Br has more protons to pull the electrons in closer. Br is smaller because it has less protons and electrons making it smaller. Br is actually larger than As because it has a larger atomic mass. Question 11 Explain why metals have lower ionization energy than nonmetals. No answer...
For which of these elements would the first ionization energy of the atom be higher than that of the diatomic molecule? beryllium,hydrogen,neon, carbon

7.90 Rank the following elements in order of increasing ionization energy: Mg, P. O. 7.91 Use electron configurations to explain why more energy is required to remove an electron from a lithium atom than from a sodium atom. 7.93 Use electron configurations to explain why the ionization energy for fluorine is greater than that for oxygen. 7.95 Write balanced equations that represent the processes that correspond to the first and second ionization energies for magnesium. 7.96 Which ionization energy (IE....
