Write the complete (from 1s) electron configuration for an element containing 28 electrons. Orbitals should be in order of relative energy (lowest to highest). Write a shortand (using noble gas core) electron configuration for an element containing 83 electrons. Orbitals should be in order of relative energy (lowest to highest).
Provide the orbital diagram, electron configuration, condensed electron configuration, and the number of unpaired electrons for ground state (a) oxygen, (b) titanium and (c) chromium. Discussion: How would you use the periodic table above to help fill the orbitals of many-electron atoms? Which atoms on the first row of the transition metals have anomalous electron configurations?
An orbital-filling diagram shows the number of electrons m each orbital, which are shown in order of energy. The placement of electrons in orbitals follows a certain set of rules. Lower energy subshells fill before higher energy subshells. The order of filling is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. The periodic table can be used to help you remember this order. An orbital can hold up to...
3. Knowing that the magnesium and aluminum atoms possesses 12 and 13 electrons respectively: (a) Write down the electron configuration (nl) of the ground state. Explain your answer. (b) We focus on the electron configuration determined in (a). Considering only the electrons from the outer subshell, add their electronic spins and their orbital angular momenta separately. Label the total spin and the total orbital momentum quantum numbers by s and l, respectively. Write down the possible values spanned by s...

In the animation, you can see that the electrons occupy different orbitals according to the energy level of each orbital. A single box represents an orbital. The unpaired electron is represented aswhereas the paired electrons in the same orbital are represented by two arrows pointing in opposite directions:. Watch the animation and identify which of the following statements are correct. Check all that apply. The He atom has two electrons that have parallel spin in its 1s orbital. In the...
1. The chromium-chromium bonding in a molecule uses the 3d orbitals of the chromium atoms. a. Draw the 3d orbitals of a chromium atom being sure to label the x, y and z axes. Standard convention is that the z-axis is parallel to the internuclear axis. b. Draw the MO energy diagram for an isolated [Cr2]2+ fragment (no ligands!) assuming the interactions of only the 3d orbitals. Assume that the z-axis is parallel to the internuclear axis c. Next to...
