What is the mass of an atom with 34 protons 34 electrons and 45 neutrons?

The mass of an atom is primarily determined by the sum of its protons and neutrons, as electrons contribute negligible mass. In this case, the atom has 34 protons and 45 neutrons, giving it a total nucleon count of 79. The Atomic Mass is approximately 79 atomic mass units (amu), assuming the mass of protons and neutrons are roughly 1 amu each. Thus, the mass of the atom is about 79 amu.
