3. Atomic physics of sodium. In the sodium atom, there is a transition between the 3s and 3p atomic states that produces the yellow-orange light seen in many street lamps a. Sodium has 11 protons and 11 electrons with ten of the electrons filling the n =1 and n = 2 levels. Including interactions between the outer electron and the electrons in the underlying shells, should the 3s or the 3p energy level have the highest energy? Use properties of...

Chemistry CHE 140, 170, 180 о Goal: With reference only to the periodic table, to write the electron configuration of the ground state (lowest energy), gaseous, atoms. Tools: (1) A list of the electronic sublevels within the atom in order of their increasing energy. (Write the list, 1s 2s 2p <6s, in the boxes below as indicated, by inspection of the "Aufbau" diagram or of the periodic table, where the order is explicit) (ii) Fill in the box below each...

The electron configuration can also be represented by writing the symbol for the occupied subshell and adding a superscript to indicate the number of electrons in that subshell. For example, consider a carbon atom having an atomic number of 6. The total number of electrons in a neutral carbon atom is 6. The electron configuration of the carbon atom represented by the orbital diagram is C= ↿⇂ 1s ↿⇂ 2s ↿ ↿ 2p This electron configuration can be written as...

Part A What is wrong with the notation 1s22s22p63s23p63d104s24p2 for germanium (atomic number 32)? The 4s subshell should appear before the 3d subshell. The 3p subshell should have more than 6 electrons. The 3d subshell can hold only 8 electrons. The 4d subshell should receive electrons before the 4p subshell. Part B Why should the 4s subshell be filled before the 3d? Why should the subshell be filled before the ? The 4s subshell has...
