multiple proportions? Why? Why not?
2. Give the number of protons, neutrons, and electrons in each of the following species:
(a) 20 1,Na, (b) 2 1,Na, (c) "0, and (d) carbon-14.
3. One isotope of a metallic element has mass number 65 and has 35 neutrons in its nucleus. The
cation derived from the isotope has 28 electrons. Write the symbol for this cation.
