Potassium-39 and potassium-41 are naturally occurring stable isotopes of potassium.

Nuclei of potassium-39 and potassium-41 can be represented by these symbols:

39K19and41K19 {}^{39}\text{K}_{19} \quad \text{and} \quad {}^{41}\text{K}_{19} 39K19​and41K19​

Complete the table for a neutral atom of potassium-39 and a neutral atom of potassium-41.
