6. Why do the expceptions of chromium and copper occur?
because they begin with the letter C
It is more favourable to have half completed shells where all the orbitals are half full or more favourable to have shells were all the orbitals are full (pairing has occured)
because it just does and no one nows why
because they both are in the same block on the periodic table
7. What block on the periodic table is calcuim in?
S
F
D
P
8. What block is the element in that contains 14 electrons?
D
F
P
S
9. There is one orbital in the S sub shell
True
False
10. Each orbital contains a maximum of 4 electrons.
