Problem: Which of the following statements is(are) true?a. F has a larger first ionization energy than does Li.b. Cations are larger than their parent atoms.c. The removal of the first electron from a lithium atom (electron configuration is 1s2 2s1) is exothermic—that is, removing this electron gives off energy.d. The He atom is larger than the H+ ion.e. The Al atom is smaller than the Li atom.

FREE Expert Solution

To solve this problem, we will look at several periodic trends. 

Let us look at each statement individually:

a. F has a larger first ionization energy than does Li.

Ionization energy is the energy needed to remove an electron from a gaseous element. The general trend for ionization energy is:
