Questions
Question #1
What is the maximum number of
electrons the d orbital can hold?

10 (because it has 5 orbitals, each
can hold 2 electrons)
Question #2

What does the angular momentum
quantum number represent?
a) orientation of electron
b) orientation of orbital
c) shape of orbital
d) energy level
Answer: c
Question #3
Why doesn’t the number of protons
change when an ion forms?

Changing the protons changes the
element/identity
