### Average Atomic Mass CalculationsThe document presents a table with two columns to calculate the average atomic mass. **Table:**1. **Headers:** - The left column is labeled "Isotope." - The right column is labeled "Mass Abundance."2. **Rows:** - There are several empty rows below the headers for data entry related to isotopes and their respective mass abundance.**Average Atomic Mass:**- Below the table, there is a line to input the calculated average atomic mass.This table is intended for use in calculating the average atomic mass of an element by listing its isotopes and their corresponding abundance in nature. To find the average atomic mass, one would multiply the mass of each isotope by its abundance, then sum these values for all isotopes. # Element: Neodymium## Isotope Data| Name of Isotope | Number of Protons | Number of Neutrons | Mass (amu) | Abundance (%) | Abundance (decimal) ||-----------------|-------------------|--------------------|------------|---------------|---------------------|| Neodymium-14 2 | | | 141.908 | | || Neodymium-14 3 | | | 142.909 | 12.2% | || Neodymium-14 4 | | | 143.910 | 23.8% | || Neodymium-14 5 | | | 144.913 | 8.3% | || Neodymium-14 6 | | | 145.913 | 17.2% | || Neodymium-14 8 | | | 147.917 | 5.7% | || Neodymium-15 0 | | | 149.921 | 5.6% | |**Note**: The table lists several isotopes of Neodymium with corresponding atomic mass units and their percentage abundance. The columns for the number of protons and neutrons are missing information. The abundance is given in percentage form, but there is an empty column labeled for decimal abundance that should ideally provide the abundance figures in the decimal format.
