The chart below gives the locations, charges, and approximate masses of three subatomic particles . The approximate mass of each particle is given in universal mass units (u). Particle Location Charge Approximate massProton Nucleus 1 +1 uNeutron Nucleus 0 1 uElectron Orbitals 1 -0 u1. The mass number of an atom is equal to the sum of protons and neutrons in the nucleus. A helium atom has 2 protons and 2 neutrons. What is the mass number of this atom? __ 4 __2. The atomic number of an element is equal to the number of protons in each atom of the element. All helium atoms have 2 protons. What is the atomic number of helium? _ 2 ___Gizmo Warm-upWhile most atoms are stable, some are radioactive , whichmeans that they have a tendency to undergo spontaneous nuclear decay . The decay of radioactive atoms generally results in
