The wrong configuration of bromine is to be analyzed. Concept Introduction: The electronic configuration is the distribution of electrons in the atom or molecule in their respective atomic or atomic orbitals by following the Aufbau principle, Pauliâ€™s exclusion, principle, and Hundâ€™s rule. Aufbau principle states that in the ground state of an atom, the electrons are filled in the orbitals in the increasing order of orbital energy level which means that the lowest energy level is filled before higher energy levels. Pauliâ€™s exclusion principle states that two electrons that represent in an atom or molecule never have the same four electronic quantum numbers. An orbital that carries a maximum of two electrons should have opposite spin which means that one electron must be up-spin and another must have a down spin. Hundâ€™s rule states that before the double occupation of any orbital, every orbital in the sub-level is singly occupied and the electron present in singly occupied orbitals possesses identical spin.

Interpretation:

The wrong configuration of bromine is to be analyzed.

Concept Introduction:

The electronic configuration is the distribution of electrons in the atom or molecule in their respective atomic or atomic orbitals by following the Aufbau principle, Pauliâ€™s exclusion, principle, and Hundâ€™s rule.

Aufbau principle states that in the ground state of an atom, the electrons are filled in the orbitals in the increasing order of orbital energy level which means that the lowest energy level is filled before higher energy levels.

Pauliâ€™s exclusion principle states that two electrons that represent in an atom or molecule never have the same four electronic quantum numbers. An orbital that carries a maximum of two electrons should have opposite spin which means that one electron must be up-spin and another must have a down spin.

Hundâ€™s rule states that before the double occupation of any orbital, every orbital in the sub-level is singly occupied and the electron present in singly occupied orbitals possesses identical spin.

compared t-critical with t-calculated and 95% confidence interval to answer this question

Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161, 165, 160, 167, 166 1+3 HNO3–HCl: 159, 145, 140, 147, 143, 156 Determine whether there is a significant difference between these methods at the 95% confidence interval.

Comparison of experimental data to “known” value. Monna and co-workers used radioactive isotopes to date sediments from lakes and estuaries.21 To verify this method they analyzed a 208Po standard known to have an activity of 77.5 decays/min, obtaining the following results. 77.09, 75.37, 72.42, 76.84, 77.84, 76.69, 78.03, 74.96, 77.54, 76.09, 81.12, 75.75 Do the results differ from the expected results at the 95% confidence interval?
