question arrange the elements in order of increasing ionization energy. use the periodic table to identify their positions on the table. drag each tile to the correct box. tiles chlorine fluorine gallium phosphorus sequence

Answer

Answer:

gallium < phosphorus < chlorine < fluorine

Explanation:

Step1: Recall ionization - energy trend

Ionization energy increases across a period and decreases down a group.

Step2: Locate elements in periodic table

Gallium (Ga) is in Group 13, Period 4; phosphorus (P) is in Group 15, Period 3; chlorine (Cl) is in Group 17, Period 3; fluorine (F) is in Group 17, Period 2.

Step3: Compare ionization energies

Gallium is a metal and has the lowest ionization energy among them. Phosphorus and chlorine are in the same period, and chlorine has a higher ionization - energy than phosphorus due to its higher effective nuclear charge. Fluorine is in the second period and has the highest ionization energy as it is a small atom with a high effective nuclear charge.
