Answer:
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.
Elements belonging to the same group have similar chemical properties. Hence elements that have similar chemical properties with the listed elements are :
- Iodine - > Fluorine, Bromine
- Barium - > Beryllium, Magnesium
- Iron - > Hassium, Osmium
Iodine belong to Group 7 on the periodic table, also called the halogen group, similar elements include chlorine, Fluorine and Bromine
Barium belongs to group 2 on the periodic table, other group 2 elements which have the same chemical properties are Calcium, Magnesium, Radium, Beryllium
Iron being group 8 and share similar chemical properties with ruthenium, Osmium and Hassium.
