This is an activity analyzing this science paper, but I don't understand how to answer the questions, expecially the first one.
High-entropy Alloys with High Saturation Magnetization, Electrical Resistivity and Malleability
How did the addition of Al and Si affect the magnetization of the alloy? Is this what you would expect, based on what you know about the magnetism of elements on the periodic table? Explain your answer.
Analyze the graph in Figure 2. Explain what the graph shows ,and summarize the conclusion you can draw from the graph.
In general, do transition metals or main group elements tend to have higher melting points? According to the article, the alloy tended to have a uniform structure when only Fe, Co, and Ni were included. With Al and Si, however, it had more segregation in its structure. How did the researchers speculate that the melting points of the elements affected the microstructures formed as the alloy solidified?
Explain the effect that the researchers felt the atomic size of aluminum had on their results. Does this match wwhat you know about the periodic trends of atomic size on the periodic table? Explain why or why not.
Thank you!
How long is this research paper? It's tough to answer questions based on this paper when we can't read the paper. Can you post the paper? Or can you post the link to allow us to see/read the paper. Only tutors are allowed to post links on this site; however you can type in the url EXCEPT leave a space between hppts: and //
I tried doing that but it didnt work.
The link is nature.com and

Would this work?
To answer these questions, it is helpful to understand the key concepts discussed in the science paper. By analyzing the paper and corresponding figures, we can find the necessary information to address each question.
1. How did the addition of Al and Si affect the magnetization of the alloy? Is this what you would expect, based on what you know about the magnetism of elements on the periodic table? Explain your answer.
To answer this question, you should look for information in the science paper regarding the effect of adding Al and Si on the magnetization of the alloy. Check the experimental procedure or the results section of the paper. Look for any discussions on the change in magnetization after adding these elements.
It is also essential to consider what you know about the magnetism of elements on the periodic table. For example, transition metals tend to be magnetic, while main group elements may or may not exhibit magnetic behavior.
After gathering this information, compare it to the findings in the paper. If the paper discusses a change in the magnetization of the alloy after adding Al and Si and it aligns with your understanding of the magnetism of elements, state that in your answer. If there is no direct information in the paper, you can make an inference based on your knowledge of the periodic table and explain your reasoning.
2. Analyze the graph in Figure 2. Explain what the graph shows and summarize the conclusion you can draw from the graph.
To answer this question, you need to analyze Figure 2 in the paper. Start by carefully observing the axes and any labels or titles provided. Determine what variables are being plotted and how they relate to each other.
Next, look for patterns or trends in the graph. Note any significant changes or relationships between the variables.
After understanding the information presented in the graph, interpret it and summarize the conclusion you can draw from it. The conclusion should be based on the data and trends observed in the graph, relating back to the main ideas presented in the paper.
3. In general, do transition metals or main group elements tend to have higher melting points? According to the article, the alloy tended to have a uniform structure when only Fe, Co, and Ni were included. With Al and Si, however, it had more segregation in its structure. How did the researchers speculate that the melting points of the elements affected the microstructures formed as the alloy solidified?
To answer this question, you can start by recalling your knowledge of the periodic trends in melting points for transition metals and main group elements. Typically, transition metals have higher melting points compared to main group elements.
Next, consider the information provided in the article about the alloy's structure. Note that when only Fe, Co, and Ni were present, a uniform structure was observed, but adding Al and Si resulted in more segregation.
Based on this information, speculate on the researchers' reasoning. They may have suggested that the differing melting points of the elements influenced the formation of microstructures as the alloy solidified. Transition metals, with their higher melting points, may have maintained a more stable and uniform structure during solidification, while the lower melting point elements, Al and Si, could have caused segregation or separation in the alloy.
4. Explain the effect that the researchers felt the atomic size of aluminum had on their results. Does this match what you know about the periodic trends of atomic size on the periodic table? Explain why or why not.
To answer this question, look for information in the science paper where the researchers discuss the effect of the atomic size of aluminum on their results. Check the sections related to the experimental procedure, discussion, or conclusions.
Then, consider your knowledge of the periodic trends of atomic size on the periodic table. Atomic size generally decreases from left to right across a period and increases from top to bottom within a group.
Compare the information from the paper with your understanding of periodic trends. If the researchers' findings and speculations align with the expected trends in atomic size, state that in your answer. Alternatively, if there is a discrepancy between the paper's results and the expected trends, explain the potential reasons or limitations that might account for this discrepancy.
Remember, when answering these questions, it is crucial to base your responses on the information and data provided in the science paper, as well as your knowledge of the relevant concepts and periodic trends.
