To determine the name of the element, we need to look at the atomic number. The atomic number is equal to the number of protons in the nucleus of an atom. In this case, the element has 19 protons, so the atomic number is 19.

Based on the periodic table, we can determine that the element with an atomic number of 19 is potassium (K). So, the name of the element is potassium.
