MODULE 6A STUDENT ACTIVITYMAKING AN IMAGINARY PERIODIC CHARTINTRODUCTIONThe following 26 elements were discovered in another far-away galaxy. Theyare symbolically represented by the letters of our alphabet and are listed inthe order of their discovery. The intrepid explorers were able to determinethe atomic masses of the elements and to group them partially into familiesof elements.PURPOSE• To design your own periodic chart.DATA OBTAINEDBY THE EXPLORERSThe Atomic Masses of the Elements in the Far-Away GalaxyA=45, B=47, C= 59, D=1, E=3, F= 13, G= 25, H= 15, I= 5, J= 7,K= 17, L= 49, M= 39, N= 21, O= 19, P= 9, Q= 11, R= 29, S= 50,T= 62, U= 63, V=53, W= 43, X= 33, Y=23, Z= 35The Groups/Families of the ElementsActive Gases: GTDLLiquids: S M E U HMetallic Solids: I K VI.I.III.IV.Transition Solids: JOR WNonmetallic Solids: X PNoble Gases: Q ZCY BV.VI.Not yet classified into groups: F ANPROCEDURE1. Using data obtained by the explorers, try to arrange the elements togetherin the form of a periodic chart.2. Put the unclassified elements in the proper positions. Predict the locationsof as yet undiscovered elements. Predict some of their properties.3. Turn in your completed chart and predictions.PICTURES IN YOUR MINDMake drawings to represent the relațive sizes of the smallest formula unit foreach of the following: LiBr, NaBr, KBr, KCI, KI, Cl2, Br2, I2.WINGS for learning © 199051

A periodic table can only be constructed with the help of the periodicity of the chemical properties…

2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.

The symbols for most elements are based on the first few letters of the respective element’s common English name. In some cases, however, the symbol seems to have nothing to do with the element’s common name.
