The minimum energy required to remove the most loosely held election is a. kinet

Question

The minimum energy required to remove the most loosely held election is a. kinetic energy b. first ionization energy. c. potential energy d. electronegativity. e. election affinity The first ionization energy of sulfur is less than that of phosphorus. A reasonable explanation for this fact involves a. the smaller size of sulfur atoms relative to phosphorus atoms. b. pairing of two elections in one 3p orbital in sulfur atoms. c. the higher electronegativity of sulfur relative to phosphorus. d. the stability of the half filled subshell in atomic sulfur. e. the case with which phosphorus attains a noble gas electronic configuration Which element has the highest first ionization energy? a. C b. O c. B d. N e. Be Arrange the following elements in order of decreasing first ionization energy. F, Be, O, N, C a. O > F > N > Be > C b. F > 0 > N > C > Be c. Be > C > 0 > N > F d. F > N > 0 > C > Be e. Be > C > N > 0 > F Which equation below depicts the reaction from which the first ionization energy would be determined? a. Ca(g) rightarrow Ca^+ (g) + e^- b. Ca(g) rightarrow Ca^2- + e^- c. Ca(s) rightarrow Ca^+ (g) + e^- d. Ca(s) + e rightarrow Ca (g) e. None of these Which of the following elements has the most negative electron affinity? a. Si b. P c. Te d. S e. Se Which of the following ions is moelectronic with a noble gas? a. Se^2- b. Mg^1+ c. P^2- d. Ca^+ e. Ba^3-

Explanation / Answer

7) b = 1st ionization energy

9) d = N

Nitrogen has highest 1st ionization energy due to half filled sub shell.

10) d

Fluorine has more 1st ionization energy than nitrogen.

11) a

1st ionization energy = removal of electron from isolated gaseous atom.
