The correct Answer is:
To answer the question regarding the trend of electropositive character of elements as we move down a group in the periodic table, we can follow these steps: ### Step 1: Understanding Electropositive Character Electropositive character refers to the ability of an element to donate electrons and form positive ions (cations). Elements with high electropositive character are typically metals. **Hint:** Remember that electropositivity is linked to how easily an element can lose electrons. ### Step 2: Observing Trends in the Periodic Table In the periodic table, as we move down a group (for example, Group 1 or Group 2), the atomic size of the elements increases. This increase in size affects the outermost electrons. **Hint:** Consider how atomic size influences the attraction between the nucleus and the outermost electrons. ### Step 3: Analyzing Ionization Energy As we go down a group, the ionization energy (the energy required to remove an electron) decreases. This is because the outermost electrons are further from the nucleus and are less tightly held due to increased shielding from inner electrons. **Hint:** Think about how the distance from the nucleus affects the energy needed to remove an electron. ### Step 4: Correlating Ionization Energy with Electropositive Character Since electropositive character is related to the ability to lose electrons, a decrease in ionization energy means that elements can more easily lose their outermost electrons as we move down a group. Therefore, the electropositive character increases. **Hint:** Link the concept of ionization energy with the ability to donate electrons. ### Step 5: Conclusion Thus, we conclude that as we move down a group in the periodic table, the electropositive character of the elements increases. **Final Answer:** The electropositive character of elements increases down a group.
