## Step 1: Understanding the Table Headers<br />### The table headers are "Relative Mass (amu)" and "Relative Electric". These headers indicate that the table is detailing properties of particles or elements, specifically their relative atomic mass and relative electric properties.<br /><br />## Step 2: Analyzing the Table Content<br />### The table content includes various particles with their respective relative masses and electric charges. The particles mentioned are likely electron, proton, and neutron based on the context provided by the headers.<br /><br />## Step 3: Translating and Interpreting the Table<br />### The table can be interpreted as follows:<br />- The first row is empty.<br />- The second row lists an electron with a charge of $-1^{0} \mathrm{e}$.<br />- The third row lists a proton with a charge of $+1$.<br />- The fourth row lists a neutron with a relative mass of $\frac{1}{\cdot \Delta Y}$.<br /><br />## Step 4: Completing the Table<br />### Based on the standard properties of these particles:<br />- Electron has a relative mass of approximately $0.000548597$ amu.<br />- Proton has a relative mass of approximately $1.007276$ amu.<br />- Neutron has a relative mass of approximately $1.008665$ amu.
