Notes: Elements with atomic weights in square brackets have no stable isotopes. Different sources list different atomic weights for elements. The difference arises from the differing atomic weights of various isotopes. We have tried to list the most stable isotope. For example, some sources list the atomic weight of seaborgium as 263 and others 266. The most stable isotope appears have an atomic weight of 266 so we list that weight here. Roentgenium is still the unofficial name of element 111 but it is the one recommended by the IUPAC so we list it here instead of the generic
‘unununium’. Aluminum, cesium, and sulfur are the American spellings for aluminium, caesium, and sulphur. This table was downloaded from http://www.science-teachers.com/printable_periodic_tables.htm

Unit 3: Atoms and Elements: Periodic Table
a. Color the NONMETALS yellowb. Color the METALLOIDS greenc. Color the METALS blued. Color the CHEMICAL SYMBOL red if it is a solid at room temperaturee. Color the CHEMICAL SYMBOL blue if it is a liquid at room temperaturef. Color the CHEMICAL SYMBOL green if it is a gas at room temperature
Make a key for each color used. Create a chart with at least three properties and an example of nonmetals, metalloids and metals. Complete on back of periodic table!
3. Label a. Label each PERIODb. Label each GROUP
4. Patterns a. Complete each card following these instructions. We will use the cards to find patterns in the periodic table
Reminder!!!
Atomic Number = # of Protons (P)
Mass Number – Atomic Number = # of Neutrons (N)
# of Protons = # of Electrons (E)
