For each of the given elements, list two other elements that have similar chemical properties. a. iodine b. barium c. iron

For A: The elements having similar chemical properties as of iodine are fluorine and bromine.

For B: The elements having similar chemical properties as of barium are magnesium and calcium

For C: The elements having similar chemical properties as of iron are ruthenium and osmium.

Explanation:

In a periodic table, elements are arranged in 18 vertical columns known as groups and 7 horizontal rows known as periods.

Elements arranged in a group show similar chemical properties because of the presence of same number of valence electrons.

For A:  Iodine

Iodine is present in Group 17 of the periodic table. The elements present in this group are Fluorine, Chlorine, Bromine, Iodine and Astatine.

The elements having similar chemical properties as of iodine are fluorine and bromine.

For B:  Barium

Barium is present in Group 2 of the periodic table. The elements present in this group are Beryllium, Magnesium, Calcium, Strontium, Barium and Radium.

The elements having similar chemical properties as of barium are magnesium and calcium

For C:  Iron

Iron is present in Group 8 of the periodic table. The elements present in this group are Iron, Ruthenium, Osmium and Hassium.

The elements having similar chemical properties as of iron are ruthenium and osmium.
