¼
2.What are at least two shared characteristics of Flourine (F) and the matching element that you selected based on their locations in the Periodic Table?
¼
3.What are at least two shared characteristics of Iodine (I) and the matching element that you selected based on their locations in the Periodic Table?
¼
4.What are at least two shared characteristics of Argon (Ar) and the matching element that you selected based on their locations in the Periodic Table?
1. Calcium and Strontium (Sr) are both alkaline earth metals located in Group 2 of the Periodic Table. They both have similar chemical properties, such as forming colorless compounds and reacting with water to release hydrogen gas.
2. Fluorine and Chlorine (Cl) are both halogens located in Group 17 of the Periodic Table. They both have high electronegativity and react vigorously with other elements to form compounds.
3. Iodine and Bromine (Br) are both halogens located in Group 17 of the Periodic Table. They both have similar physical properties, such as being diatomic nonmetals with distinct colors (iodine is purple, bromine is red-brown).
4. Argon and Neon (Ne) are both noble gases located in Group 18 of the Periodic Table. They both have complete outer electron shells, making them inert and nonreactive with other elements.
