Task

Display the row and column in the periodic table of the given atomic number.

The periodic table

Let us consider the following periodic table representation.

Example test cases;
   1 -> 1 1
   2 -> 1 18
   29 -> 4 11
   42 -> 5 6
   57 -> 8 4
   58 -> 8 5
   72 -> 6 4
   89 -> 9 4
Details;
The representation of the periodic table may be represented in various way. The one presented in this challenge does have the following property : Lantanides and Aktinoides are all in a dedicated row, hence there is no element that is placed at 6, 3 nor 7, 3.

You may take a look at the atomic number repartitions here.

The atomic number is at least 1, at most 118.

PeriodicTable_Column:
db $ff,$01,$18,$01,$02,$13,$14,$15,$16,$17,$18,...         ;I don't need to write them all out, the concept is self-explanatory enough.
