PPT-Assessing atomic data accuracy along isoelectronic

sequences Peter Young George Mason University VA Uri Feldman Artep Inc MD Work funded by NSF and NASA The CHIANTI atomic database Atomic data and software package for modeling . At the start of WWII in 1939 the atomic bomb had not yet been invented. However, scientists discovered about that time that a powerful explosion might be possible by splitting an atom. This type of bomb could destroy large cities in a single blast and would change warfare forever!. Bell Ringer . Review..Frame. your argument. Bell Ringer: What was the name of the program to build the Atomic Bomb? Who was the lead scientist?. Agenda: Notes/discussion. Objective: Through Discussion and notes students will begin to understands the steps leading to the dropping of the atomic bomb.. #1: Rubidium has two common isotopes, . 85. Rb and . 87. Rb. . If the abundance of . 85. Rb is 72.2% and the abundance of . 87. Rb is 27.8%, what is the average atomic mass of rubidium?. PROCEDURE:. Chapter . 5.1 . Dat. a Screening. Data Screening.

Informed FDR of recent developments in splitting uranium atoms. Could lead to “extremely powerful bombs of a new type” by means of nuclear fission. Nucleus absorbs a neutron, breaks into two equal fragments. CONTEXT. There are two . contexts precision . and accuracy apply to: sets of data, and measuring instruments.. In a set of data, those measures give an idea of the spread and “. ballpark. ” of the answer (final measurement).. Antonio Brathwaite. and Michael Duncan .
