The correct Answer is:
To determine the most electropositive element among the given options, we need to understand the concept of electropositivity and how it relates to the periodic table. ### Step-by-Step Solution: 1. **Understanding Electropositivity**: - Electropositivity refers to the ability of an element to donate electrons. Metals tend to be electropositive, and their electropositivity increases as we move down a group in the periodic table. 2. **Analyzing the Options**: - (A) Sodium (Na): This is an alkali metal located in the 3rd period. - (B) Copper (Cu): This is a transition metal located in the 4th period. - (C) Cesium (Cs): This is an alkali metal located in the 6th period. - (D) Calcium (Ca): This is an alkaline earth metal located in the 4th period. 3. **Comparing the Elements**: - Alkali metals (like Na and Cs) are generally more electropositive than alkaline earth metals (like Ca). - Among the alkali metals, electropositivity increases as we move down the group. Therefore, Cs (cesium) being in the 6th period will be more electropositive than Na (sodium) in the 3rd period. 4. **Conclusion**: - Since cesium (Cs) is in the lowest position among the options provided and is an alkali metal, it is the most electropositive element. Thus, the answer is **(C) Cs**.
