Exam 8: Electron Configuration and Chemical Periodicity

Select the element with the most negative electron affinity (i.e., accepts an electron most readily).

Write down the maximum number of electrons in an atom which can have a. quantum number n = 4. b. orbital designation 3d. c. orbital designation 2p_z.

In forming ions of the first series of transition metals, the 4s electrons are lost before the 3d electrons.

What is the correct order of decreasing size of the following ions?

Select the correct electron configuration for Cu (Z = 29).
