At low atomic numbers, stable atomic nuclei have roughly equal numbers of protons and neutrons (a ratio of 1:1). How does the neutron/proton ratio change for stable nuclei as the atomic number increases? What is the approximate n:p ratio for elements near the end of the Periodic Table (atomic numbers above 80)?
as the number of protons and neutrons in the nucleus increases, elements are much less likely to form stable, non-radioactive isotopes. Of elements that form non-radioactive isotopes, which has the highest atomic number? Choices: bismuth iron radium uranium

Atoms and Isotopes 1 Activity: Atoms and Isotopes Why? Atoms and isotopes are identified by the numbers of protons, electrons, and neutrons that they contain The number of protons, electrons, and neutrons in atoms determines the chemical properties of the elements .A knowledge of the number of protons and electrons in an atom will help you understand how atoms combine to form molecules Identify the composition of atoms in terms of protons, neutrons, and electrons Use atomic symbols to represent...
