Question
[VISUAL]
- The first ionization energy of an element is the energy required to remove an electron from a gaseous atom of the element (i.e., X(g) → X+(g) + e−). The values of the first ionization energies for the third-row elements are shown in the graph above. On the basis of the information given, which of the following reactions is exothermic?
A.
Cl(g) + Mg+(g) → Cl+(g) + Mg(g)
B.✓ Correct
Al(g) + Mg+(g) → Al+(g) + Mg(g)
C.
P(g) + Mg+(g) → P+(g) + Mg(g)
D.
S(g) + Mg+(g) → S+(g) + Mg(g)
