Solution: The first ionization energies of the elements __________ as you go from left to right across a period of the periodic table, and __________ as you go from the bottom to the top of a group in the table

Problem

The first ionization energies of the elements __________ as you go from left to right across a period of the periodic table, and __________ as you go from the bottom to the top of a group in the table.

A) increase, increase

B) increase, decrease

C) decrease, increase

D) decrease, decrease

E) are completely unpredictable

Solution

Establish the definition of ionization energy and determine the proper words for the blank statements

Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

The trend of the ionization energies of the elements can be observed in the periodic table:
