Calculate how many protons, electrons and neutrons there are in:a) A silver atom with atomic number 47 and mass number 108

Answer: Protons = 47 Electrons = 47 Neutrons = 61Explanation: An atom contains equal numbers of protons and electrons. Atoms have no overall electrical charge because the number of positive protons equals the number of negative electrons. Number of protons = atomic number.All atoms of an element have the same number of protons. Atoms of different elements have different numbers of protons.Atomic Number = Number of Protons OR Electrons Mass Number = Number of Protons AND Neutrons
