2 cards from this section. Quick, good the night before a test.
What is the general filling order for atomic orbitals?
Think about which orbitals are filled first in transition metals.
Which electrons are lost first when a transition metal becomes a cation?
Check the order of filling you just learned.
What orbital is filled before the (n−1)d orbital in transition metals?
Remember the order of filling you learned in class.
True or False: Chromium has a fully filled d subshell.
Think about the electron configuration of chromium.
Given the electron configuration of a transition metal, identify its common oxidation states based on its filling order.
Refer to how many d electrons are present and how they correspond to metal reactivity.
Explain how the instability of certain configurations leads to the preference for cation formation in transition metals.
Relate back to half-filled vs. filled subshell stability.
