Electron affinity is the energy released when an electron is added to the gaseous atom or ion.
Electron affinity increases by moving from left to right in periodic table and decreases by moving from up to down.
So the correct answer is Te
Xe: being as noble gas it is unacceptable to gain an electron
The values of electron affinity for these elements:
Ba (13.9 kJ/mol) - Te (190.1 kJ/mol) - Xe (-80 kJ/mol) - Cs (45.5 kJ/mol)

The statement “Only the “Conclusion” section discusses whether the original hypothesis was supported, and both sections suggest further research”, best describes the difference between analysis and conclusion.
Answer: Option 4
<u>Explanation:
</u>
In research, we do experiments and derive the results. Then, those results were analyzed by us. In this analysis part, we compare our results with the related results published elsewhere. Also, we correlate the similarities and point out the differences between our analysis and other reported results.
In conclusion part, we have to check hypothesis or it supported. And, we summarise our analysis and figure out the further research need to be done on that to improvise our research. So, the final statement is the correct option which best describes the difference between analysis and conclusion.
Answer:
Sand
Explanation:
with salt distillation will work, heat the solution and collect the water in a seperate beaker
With sugar you do the same, boil away the water and collect the water vapour, you'll be left with sugar in the original container and water if you collected it
Use a fraction of column and heat the solution, the alcohol will be seperated out
Sand is the only one that uses mechanical filtration
