*Parts of an Atom

Label the subatomic particles in an atom. protons neutrons electrons Match the subatomic particles to their charge. neutron neutral (0) electron negative (1-) proton positive (1+) How many neutrons are in the nucleus of an atom with an atomic number of 25 and a mass number of 51? 25 51 26 76 What is the mass number of an atom with 5 protons, 8 neutrons, and 4 electrons? 5 8 9 13 The following table contains elements with atoms in their neutral states.
