a) Write the full electron configuration for the sodium atom. b) Label and provide a point form explanation for each of the significant parts of the electron configuration.

How do you calculate the number of electrons in the outer shell?

Give the "box notation" (also called the "dash notation") electron configuration of F- by filling electrons into the orbital spaces provided. Press Check when complete. Add either a single electron or a pair of electrons to an orbital by clicking and dragging the arrow symbol onto the dash. To remove electrons from an orbital, click on the orbital.

Identify the general outer electron configuration for each group of elements shown in this periodic table outline. Drag each label to the appropriate target.

Please don't provide handwritten solution ....

Using the periodic table, enter the electron configuration of V.

Please I really need help solving #2 question A.

For each atom give the electron configuration in spectroscopic notation.

For multi-electron atoms, we use the shell model and effective corepotential to estimate the energy of each atomic orbitals.a)  For carbon anion (C-1), estimate the energy of 1s and 2s atomic orbitals.b) Draw the energy level diagram and assign electrons for carbon anion(C-1).c)  In one or two sentences, briefly describe what is the physical meaningof atomic orbitals.d) Lydia sets up a photoelectron spectroscopy experiment of the gaseouscarbon anion (C-1) using an UV light (λ = 300 nm). How many peaks do you expect to see in the final spectrum?e)  Estimate the lowest kinetic energy of the ejected electrons.

If possible what is the ionization energy value for He ?
