02: Atoms, Molecules, and IonsDue: 11:30pm on Wednesday, October 6, 2010Note:You will receive no credit for late submissions.To learn more, read your instructor's Grading Policy[Switch to Standard Assignment View]Please review the Chapter 2 notes in htmlor pdfbefore proceeding to the below graded activities/problems.IsotopesPeriodic tableThe periodic table lists two main numbers for each element. The atomic numberis an integer that equals the number of protons. The number ofneutrons is not given in the periodic table because it will vary with different isotopes. The mass numberof an element is the sum of the protons andneutrons. This also is not given in the periodic table because it varies with each isotope. What we do see is the atomic mass, or a weighted averageof all the isotope masses. This is the noninteger listed with an element; it is the number with several decimal places.Elemental symbolWhen writing the symbol for an element, a superscript indicates the mass number and a subscript indicates the atomic number. For example, hasa mass number of 14 and an atomic number of 6. This isotope can also be written as just . You do not need to put in the 6 because the atomicnumber of carbon is always 6 regardless of which isotope you are dealing with.Part AHow many neutrons are found in one atom of ?Hint A.1How to approach the problemHint not displayedHint A.2Determine the number of protonsHint not displayedANSWER:21CorrectneutronsMasteringChemistry: Assignment Print Viewhttp://session.masteringchemistry.com/myct/assignmentPrintView?assignmentID=13879511 of 349/28/2010 3:28 PM
