Homework 4 Write a one paragraph summary about the Bulletin of Atomic Scientists Doomsday Clock that was introduced by Robert Oppenheimer Click here After creating the nuclear bomb in 1945 J Robert Oppenheimer realized what he created and wanted to warn everybody about the risk of nuclear destruction The doomsday clock symbolizes how unchecked the world s nuclear programs are the closer we get to midnight the more at risk we are to nuclear destruction When it was created in 1947 the clock was 7 mins to midnight but it has moved 25 times from the farthest of 17 minutes to midnight 1991 1995 to 90 seconds 2023 present We are currently as of 2024 the closest we have ever been to midnight this is due to the war in Ukraine Climate change and the development of AI Data mine the Chart of the Nuclides for the following information on elements used in nuclear applications 1 Naturally occurring isotopes and their natural abundances 2 Atomic masses of isotopes in atomic mass units amu for the following elements a Uranium U 1 Naturally occurring isotopes and their natural abundances U 234 0 0055 U 235 0 720 U 238 99 2745 2 Atomic masses of isotopes in atomic mass units amu U 234 234 0409456 0 0000021 amu U 235 235 0439231 0 0000021 amu U 238 238 0507826 0 0000021 amu b Thorium Th 1 Naturally occurring isotopes and their natural abundances i Th 232 100 2 Atomic masses of isotopes in atomic mass units amu Th 232 232 0380504 0 0000022 amu 1 Naturally occurring isotopes and their natural abundances i c Carbon C 2 Atomic masses of isotopes in atomic mass units amu C 12 98 89 C 13 1 11 C 12 12 amu C 13 13 0033548 amu i ii iii i ii iii i ii i ii d Hydrogen H 1 Homework 4 1 Naturally occurring isotopes and their natural abundances i ii H 1 99 985 H 2 0 015 2 Atomic masses of isotopes in atomic mass units amu i ii e Lead Pb H 1 1 0078250 amu H 2 2 0141018 amu 1 Naturally occurring isotopes and their natural abundances Pb 204 1 4 Pb 206 24 1 Pb 207 22 1 Pb 208 52 4 i ii iii iv i ii iii iv i i i ii i ii 2 Atomic masses of isotopes in atomic mass units amu Pb 204 203 9730288 0 0000031 amu Pb 206 205 9744490 0 0000031 amu Pb 207 206 9758806 0 0000031 amu Pb 208 207 9766359 0 0000031 amu f Beryllium Be 1 Naturally occurring isotopes and their natural abundances i Be 9 100 2 Atomic masses of isotopes in atomic mass units amu Be 9 9 0121821 0 0000004 amu 1 Naturally occurring isotopes and their natural abundances i g Lithium Li i ii Li 6 7 5 Li 7 92 5 2 Atomic masses of isotopes in atomic mass units amu i ii h Sodium Na Li 6 6 0151223 0 0000005 amu Li 7 7 0160040 0 0000005 amu 1 Naturally occurring isotopes and their natural abundances Na 23 100 2 Atomic masses of isotopes in atomic mass units amu Na 23 22 9897697 0 0000002 amu i Boron B 1 Naturally occurring isotopes and their natural abundances B 10 19 9 B 11 80 1 2 Atomic masses of isotopes in atomic mass units amu B 10 10 0129370 0 0000004 amu B 11 11 0093055 0 0000005 amu j Cadmium Cd 1 Naturally occurring isotopes and their natural abundances 2 Homework 4 i ii iii iv v vi vii viii Cd 106 1 25 Cd 108 0 89 Cd 110 12 49 Cd 111 12 80 Cd 112 24 13 Cd 113 12 22 Cd 114 28 73 Cd 116 7 49 2 Atomic masses of isotopes in atomic mass units amu i ii iii iv v vi vii viii k Fluorine F Cd 106 105 9064580 0 0000065 amu Cd 108 107 9041834 0 0000061 amu Cd 110 109 9030056 0 0000032 amu Cd 111 110 9041816 0 0000032 amu Cd 112 111 9027572 0 0000030 amu Cd 113 112 9044009 0 0000030 amu Cd 114 113 9033581 0 0000030 amu Cd 116 115 9047554 0 0000035 amu 1 Naturally occurring isotopes and their natural abundances F 19 100 i i 2 Atomic masses of isotopes in atomic mass units amu F 19 18 9984032 0 0000001 amu 3
