For example, all calcium atoms have an atomic number of 20 but there are three
isotopes of calcium - 39, 40, and 42. (How many neutrons does each isotope
possess?) ... For element 11 (Sodium - Na) there are 11 electrons and 11 protons
The atoms of different elements have different numbers of protons. For example,
all oxygen atoms have 8 protons and all sodium atoms have 11 protons.
