13. Suppose that one volume of gas A (4 particles) combined with two volumes of gas B (4 particles each) to form one volume of product when measured at the same pressure and temperature. How many particles will the particle diagram for molecules of the product gas will have? assume gases A and B are monatomie. SOK

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.
