What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
