Question

question 2. select the correct answers from the drop-down menu for each statement about ionization energy. a) sodium (na) has a ionization energy compared to magnesium (mg). b) fluorine (f) has a ionization energy compared to iodine (i).

Explanation:

For part (a): Ionization energy generally increases across a period. Sodium (Na) and Magnesium (Mg) are in the same period (period 3), with Na having an electron configuration that is more likely to lose an electron (lower ionization energy) compared to Mg. So Na has a lower ionization energy than Mg.

For part (b): Ionization energy generally decreases down a group. Fluorine (F) and Iodine (I) are in the same group (group 17), with F being higher up in the group. Atoms higher up in a group have smaller atomic radii and hold electrons more tightly, so F has a higher ionization energy than I.

Answer:

a) lower
b) higher
