You are encouraged to solve this task according to the task description, using any language you may know.
- 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.

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.

6502 Assembly
A lookup table is the simplest solution, for the following reasons:
- The input value is guaranteed to be between 0 and 255
- The data doesn't fit a pattern that the CPU can easily take advantage of.
Since the 6502 can't index an array larger than 256 bytes, we'll store all the "low bytes" in one table and all the "high bytes" in another. Both tables share the same index, so this lets us store up to 255 possible elements while taking the same amount of memory as a single table of 16-bit values. Right now, we can do this either way, but since we're close to 128 elements, may as well future-proof the code, right?
Lookup: ;INPUT: X = atomic number of the element of interest.
LDA PeriodicTable_Column,x
STA $20 ;store column number in memory (I chose $20 arbitrarily, you can store it anywhere)
LDA PeriodicTable_Row,x
STA $21 ;store row number in memory
RTS
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.
PeriodicTable_Row:
db $ff,$01,$01,$02,$02,$02,$02,$02,$02,$02,$02,...68000 Assembly
A lookup table is the simplest solution, as the data of interest doesn't have a pattern that a computer can take advantage of easily. It's quicker than using a formula, but takes up more memory as a result.
The table consists of 118 16-bit values. The high byte is the row number, the low byte is the column number. Both are stored as binary-coded decimal (i.e. hex values that look like base 10 numbers.)
Lookup:
;input: D0.W = the atomic number of interest.
LEA PeriodicTable,A0
ADD.W D0,D0 ;we're indexing a table of words, so double the index.
MOVE.W (A0,D0),D0 ;D0.W contains row number in the high byte and column number in the low byte.

Basically, here, we want a lookup table. For example:
PT=: (' ',.~[;._2) {{)n
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

8 Lantanoidi* La Ce Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb Lu

}}
ptrc=: {{
tokens=. (#~ (3>#)@> * */@(tolower~:toupper)@>) ~.,;:,PT
ndx=. (>' ',L:0' ',L:0~tokens) {.@I.@E."1 ,PT
Lantanoidi=. ndx{+/\'*'=,PT
Aktinoidi=. ndx{+/\'-'=,PT
j=. 13|3*Lantanoidi+3*Aktinoidi
k=. {:$PT
0,}."1/:~j,.(<.ndx%k),.1+(/:~@~. i. ])k|ndx
}}
rowcol=: ptrc''
In other words, start with a hand crafted representation of the periodic table. Elements here are tokens with 1 or 2 letters. Locate the position of each token in the table. Get an initial row and column number from the character positions in the table. Translate character column to periodic table column by enumerating the unique (sorted) list of column numbers and using the index in that list. Character row was already periodic table row. Most elements here were already in atomic number order, and we can fix the exceptions by temporarily prefixing each row,col value and sorting. (Here, we use 0 for the first 56 elements, 3 for the next 17 elements (after Lantanoidi, before Aktinoidi), 12 for the next 15 (after Aktinoidi), 2 for the next 15 (the Lantanoidi) and 11 for the final 15 elements (the Aktinoidi).)

The following is a minimal recursive implementation. It calculates the position of the requested element by the position of the previous element.

((= n 2) '( 1 . -17))
((= n 4) '( 0 . 11))

(define (position n)

For successive calculations the above code is inefficient, because the position of 58 gets calculated by recalculating the position of 57, although is has already been calculated in the previous step. This can be enhanced by the use of memoization. The result of each calculation gets stored and whenever a position has to be calculated, the already calculated value gets used instead.
(define position*
(let ((memo (make-vector 118 #f)))
(lambda (n)
(let* ((mi (- n 1))
(mp (vector-ref memo mi)))
(or mp
(let ((p (position n)))
(vector-set! memo mi p)

There is a discrepancy between how the periodic table is arranged in the Wikipedia article and how it is arranged in the task description. I've used the latter in the following script.
import "./fmt" for Fmt
var limits = [3..10, 11..18, 19..36, 37..54, 55..86, 87..118]
var periodicTable = Fn.new { |n|
if (n < 1 || n > 118) Fiber.abort("Atomic number is out of range.")
if (n == 1) return [1, 1]
if (n == 2) return [1, 18]
if (n >= 57 && n <= 71) return [8, n - 53]
if (n >= 89 && n <= 103) return [9, n - 85]
var row
var start
var end
for (i in 0...limits.count) {
var limit = limits[i]
if (n >= limit.from && n <= limit.to) {
row = i + 2
start = limit.from
end = limit.to
break
}
}
if (n < start + 2 || row == 4 || row == 5) return [row, n - start + 1]
return [row, n - end + 18]
}
for (n in [1, 2, 29, 42, 57, 58, 59, 71, 72, 89, 90, 103, 113]) {
var rc = periodicTable.call(n)
Fmt.print("Atomic number $3d -> $d, $-2d", n, rc[0], rc[1])
}- Output:
Atomic number 1 -> 1, 1 Atomic number 2 -> 1, 18 Atomic number 29 -> 4, 11 Atomic number 42 -> 5, 6 Atomic number 57 -> 8, 4 Atomic number 58 -> 8, 5 Atomic number 59 -> 8, 6 Atomic number 71 -> 8, 18 Atomic number 72 -> 6, 4 Atomic number 89 -> 9, 4 Atomic number 90 -> 9, 5 Atomic number 103 -> 9, 18 Atomic number 113 -> 7, 13
