Gen Chem Unit 3The Atom and Periodic TableTrends in the Periodic Table Graphing ActivityThe arrangement of elements in the periodic table reveals many important trends, orpatterns, in the properties of elements. Many of the trends shown by the table are periodic. Thatis, they repeat within the table. For example, a periodic trend may involve low values at the topof a group, high values at the bottom, and low, values once again at the top of the next group.Recall that the atomic number of an element is equal to the number of protons in thenucleus. The atomic mass is the average number of protons and neutrons in the nucleus of anelement. Atomic radius is the distance from the center of an atom to the outermost electrons ofthe atom. The first ionization energy of an element is the energy needed to remove the mostloosely help electron of an atom of the element.Directions: You will be making three graphs in this assignment1. Using the periodic table that follows, make a graph of ATOMIC MASS vs. ATOMICNUMBER using the atomic number of 3 to 20 only. Use a different color for each period of theperiodic table.

Gen Chem Unit 3The Atom and Periodic TableAlien Periodic TableIntroduction:Imagine that scientists have made radio contact with life on a distant planet. The planet iscomposed of many of the same elements as are found on Earth. However, the inhabitants of theplanet have different names and symbols for the elements. The radio transmission gave data onthe known chemical and physical properties of 30 elements that belong to Groups 1, 2, 13, 14,15, 16, 17, and 18. You need to place the elements into a blank periodic table based on theseproperties.Problem: Where do the alien elements fit in the periodic table?Procedure:1. Listed below are data on the chemical and physical properties of the 30 elements. Write theelements in their proper position in the blank periodic table.2. Once you have determined the proper position for each element, then write the symbol in thecorrect place. The noble gases are bombal (Bo), wobble (Wo), jeptum (J), and logon (L). Among thesegases, wobble has the greatest atomic mass and bombal the least. Logon is lighter thanjeptum.The most reactive group of metals are xtalt (X), byyou (By), chow (Ch), and quackzil(Q). Of these metals, chow has the lowest atomic mass. Quackzil is in the same periodas wobble.Apstrom (A), vulcania (V), and kratt (Kt) are nonmetals whose atoms typically gain orshare one electron. Vulcania is in the same period as quackzil and wobble.The metalloids are ernst (E), highho (Hi), terriblum (T), and sississ (Ss). Sississ is themetalloid with the greatest atomic mass. Ernst is the metalloid with the lowest atomicmass. Highho and terriblum are in Group 14. Terriblum has more protons than highho.Yazzer (Yz) touches the zigzag line, but it's a metal, not a metalloid.The lightest element of all is called pfsst (Pf). The heaviest element in the group of 30 iseldorado (El). The most chemically active nonmetal is apstrom. Kratt reacts with byyouto form table salt.The element doggone (D) has only 4 protons in its atom.Floxxit (Fx) is important in the chemistry of life. It forms compounds of long chains ofatoms. Rhaatrap (R) and doadeer (Do) are metals in the fourth period, but rhaatrap is lessreactive than doadeer.Magnificon (M), goldy (G), and sississ are all members of Group 15. Goldy has fewertotal electrons than magnificon.31

Gen Chem Unit 3The Atom and Periodic TableUrrp (Up), oz (Oz), and nuutye (Nu) all gain 2 electrons when they react. Nuutye isfound as a diatomic molecule and has the same properties as a gas found here in Earth'satmosphere. Oz has a lower atomic number than urrp.The element anatom (An) has atoms with a total of 49 electrons. Zapper (Z) and pie (Pi)lose two electrons when they react. Zapper is used in flashbulbs.Analysis Questions:1. List the name of each alien element and the Earth element that it represents. Do this for all30 elements used in this activity. (write small)2. Were you able to place some elements within the periodic table with just a single clue?Explain your answer using two examples from the activity.3. Why did you need two or more clues to place other elements? Explain your answer using onespecific example from the activity.4. Why could you use clues about atomic mass to place elements, even though the periodictable is based on atomic number?32
