the variables for part ii of this experiment include the type of material used and the thermal energy transferred by
that material. use the drop-down menus to complete the sentences and identify the independent and dependent
variables
the independent variable, the one that is intentionally manipulated, is the

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

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.
