C Revi Atomic mass Since the number of neutrons varies in the periodic table, neither then number of neutrons no neutrons plus protons) is shown. What we do see is the atomic mass, or a weighted average the noninteger listed with an element; it is the number with several decimal places. An elemer average of the isotope masses. In other words, it is an average that takes into account the pe the weighted average, multiply each isotopic mass by its relative abundance and find the sum

MODULE 6 A STUDENT ACTIVITY MAKING AN IMAGINARY PERIODIC CHART INTRODUCTION The following 26 elements were discovered in another far-away galaxy. They are symbolically represented by the letters of our alphabet and are listed in the order of their discovery. The intrepid explorers were able to determine the atomic masses of the elements and to group them partially into families of elements. PURPOSE • To design your own periodic chart. DATA OBTAINED BY THE EXPLORERS The Atomic Masses of the Elements in the Far-Away Galaxy A=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= 35 The Groups/Families of the Elements Active Gases: GTDL Liquids: S M E U H Metallic Solids: I K V I. I. III. IV. Transition Solids: JOR W Nonmetallic Solids: X P Noble Gases: Q ZCY B V. VI. Not yet classified into groups: F AN PROCEDURE 1. Using data obtained by the explorers, try to arrange the…

Finding atomic mass from isotope mass and natural abundance A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope 119 S Sn 118 Sn Sn mass relative (amu) abundance 118.9 93.3% Explanation 117.9 Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. 6.7% X Check 3 ? O ol Ar ve Graw Hill LLC.
