2. Atoms are made up of a _____________ composed of protons and neutrons and a
number of electrons orbiting in shells or _____________.
3. It is the number of protons, neutrons, and electrons in an element’s atoms that determines
its ______________. The configuration of the three particles is the only thing that makes
one element _______________ from another.
4. The modern table organizes elements so it is easier to see how elements are
_____________ to each other. The elements are listed by the _____________
___________, or the number of protons in the atom’s nuclei. The table also lists the
elements _____________, name, and ___________ _________.
5. Each shell can hold only a certain number of _____________. The number of electrons
in an atom’s outer shell plays an important role in that atom’s properties determining what
other kinds of atoms it can ___________ with. Atoms bond together in molecules by either
___________ ___ or ___________ electrons. ________________ describe the number of
electrons in the outer shell.
6. Because atoms with similar numbers of electrons in outer shells behave in similar ways, you can also read the

7. The periodic table is also organized by _____________ into different categories. These categories are
organized by properties of the elements.
8. Some periodic tables may show elements all the way up to number _________, but any element over Uranium
number ______ is too unstable to occur in nature and must be made in a lab.
