Question

view available hint(s) reset help silver phosphorus germanium strontium molybdenum highest ionization energy lowest ionization energy the correct ranking cannot be determined. submit

Explanation:

Step1: Recall ionization energy trends

Ionization energy generally increases across a period (left to right) and decreases down a group (top to bottom) on the periodic table.

Step2: Locate elements on periodic table

• Phosphorus (P): Period 3, Group 15
• Germanium (Ge): Period 4, Group 14
• Silver (Ag): Period 5, Group 11
• Molybdenum (Mo): Period 6, Group 6
• Strontium (Sr): Period 5, Group 2

Step3: Rank by trend application

Nonmetals have higher ionization energy than metals. Phosphorus (nonmetal) has the highest. Among metals, ionization energy increases across a period and decreases down a group: Sr (Group 2, Period 5) has the lowest, followed by Mo (Period 6, Group 6), then Ag (Period 5, Group 11), then Ge (Period 4, Group 14).

Answer:

Highest ionization energy: phosphorus
: germanium
: silver
: molybdenum
Lowest ionization energy: strontium
