The atomic number of an element is determined by the number of protons present in its nucleus. In this case, the element has 6 protons.
Regardless of the number of neutrons or electrons, the atomic number remains the same, as it is solely based on the proton count. For this element, since it has 6 protons, its atomic number is 6.
This also means that the element in question is carbon, which is well-known for having 6 protons, 6 electrons (when neutral), and varying numbers of neutrons in its isotopes. In this specific instance, with 7 neutrons, it would represent carbon-13, a stable isotope of carbon.
