Atomic Structure Protons, Neutrons, and Electrons Section 4.3 Distinguishing Among Atoms Just as apples come in different varieties, a chemical element can come in different “varieties” called isotopes. 4.3 Protons Protons- determine the identity of an atom –Elements are different because they each...
Within the atom are three basic subatomic particles: protons (p+), neutrons (n0), and electrons (e–). We abbreviate the proton as p+ because it has a positive charge, the neutron as n0 because it is neutral, and the electron as e– because it has a negative charge. Mass (kg) Mas...
