Some people are advised to take magnesium supplements. Could you use the technique you used in this experiment to measure the amount of Mg2+ ion in a magnesium sulfate supplement tablet? Why or why not?

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
