13. Of the Average Atomic Mass, Atomic Number, and Mass Number, which of the above can be found on the periodic table? 14. Where is most all of the mass (Over 99.99999% ) of an atom located? 15. Where is most all of the volume (Over 99.99999% of the atom located? 16. Write/draw me the isotope notation for Sodium, with a mass number of 23, and a+ charge.

# Explanation:## Step1: Identify which properties can be found on the periodic table### The periodic table typically displays the atomic number and the average atomic mass of elements. The mass number is not usually listed because it can vary due to different isotopes.## Step2: Determine the location of most of the mass in an atom### Most of the mass of an atom is concentrated in its nucleus, which contains protons and neutrons.## Step3: Determine the location of most of the volume in an atom### Most of the volume of an atom is occupied by the electron cloud, which surrounds the nucleus.## Step4: Write the isotope notation for Sodium with a mass number of 23 and a positive charge### The isotope notation for Sodium with a mass number of 23 and a positive charge ( ) is written as: # Answer:### 13. Atomic Number and Average Atomic Mass### 14. In the nucleus### 15. In the electron cloud### 16.
