Question

Says my answer was wrong, but the order seems correct. It said that there is an exception and it occurs when new subshells are occupied, but I don't know what it means by that.

Arrange these elements according to first ionization energy.
Highest ionization energy
Kr
Br
Se
As
Ge
Ga
Ca
K
Lowest ionization energy

Hint
There is a general trend for ionization
energy within a period of the periodic
table. However, elements with a filled s
or half-filled p subshell have higher
ionization energies than expected by
the general trend.

The atom with the ns² electron
configuration is particularly stable and
therefore has a higher ionization energy
than the element directly to the right of
it in the periodic table.
