Give the full electron configurations of:     As

Which of the following is a set purely of atomic orbitals? Os, p, d, f, sigma O s, p. sp³, sp², sp Osigma, sigma*, pi, pi* 3 Os, p, sigma, pi, sp³

Most stable electron ion configuration for Magnesium?

9. Rank the following atoms and ions in in terms of increasing radius. Briefly explain your reasoning. Se²- Br Br Cl

If possible attempt to ionize Rb by pulling a valence electronfrom the electron shell. Describe what happened. (Were you successful? Was it “easy” to remove the electron? Did the atom seem to have a strong hold on the electron?)

Order the elements S, CI, and F in terms of increasing ionization energy. (lowest to highest) OF, S, CI O CI, F, S OF, CI, S OS, CI, F O S, F, CI

2) Write the full electron configuration for each ion. a) F b) K* c) Cu* *

Tantalum metal packs in body centered arrangement of atoms. What is the Z number?

Review Question 11.6 Explain the reason that an atom of helium has a much higher first ionization energy than does an atom of hydrogen. Helium has a much higher first ionization energy than does hydrogen because structure, consisting of a filled principal energy level. has a very stable outer electron

would you predict that Sc is metallic? Explain the basis for your predicition by using what you know about its location in the Periodic Table.
