Question 48

Zinc (Zn) is the element in Group 12.

Zinc (Zn) is classified in Group 12 of the periodic table, which is known for containing transition metals. This group includes elements that share similar properties, and zinc is well-known for its applications in galvanization and alloy production.

A) Lead (Pb)

Lead (Pb) is located in Group 14 of the periodic table, not Group 12. It is a heavier element with different chemical properties compared to the elements in Group 12, which primarily include transition metals.

B) Polonium (Po)

Polonium (Po) is found in Group 16. This element is a metalloid and is part of the chalcogen family, which includes oxygen and sulfur, making it distinct from the elements in Group 12.

C) Astatine (At)

Astatine (At) is located in Group 17 of the periodic table. It is a halogen and possesses properties that differ significantly from those of Group 12 elements, which are characterized by their metallic characteristics.

D) Zinc (Zn)

Zinc (Zn) is indeed the correct answer, as it is the only element listed that belongs to Group 12. It exhibits properties typical of transition metals, such as good conductivity and malleability.

Conclusion

Zinc (Zn) is definitively the correct answer as it is the only element in the provided choices that belongs to Group 12. Other options, including lead, polonium, and astatine, are located in different groups of the periodic table, which confirms that they do not share the same chemical characteristics or classification as zinc.
