Explain how the periodic table was originally put together and how Moseley changed it. (8 points) Mendeleev arranged the elements by atomic mass. Moseley arranged it by number of protons. 3. Explain what you have learned about how the periodic table is put together. What do elements in the same column or the same row of the periodic table have in common? What do the trends in atomic size, electronegativity, and ionization energy of elements have to do with the periodic table? (9 points) The columns on the periodic table are called groups and the elements in the same group have the same amount of electrons and valence electrons. The element’s trends also are organized in the table. 4. When there are more protons in an atom, why does the size of an atom shrink? What does the number of protons have to do with the trend in atomic size in a row of the periodic table? Why is the

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
