There are two, it says so in the wikipedia article. Quote down below.
"In music, a whole-tone scale is a scale in which each note is separated from its neighbors by the interval of a whole tone. In twelve-tone equal temperament, there are only two complementary whole-tone scales, both six-note or hexatonic scales:"
I could be wrong, best to check it for yourself.
To determine the number of versions of a whole-tone scale, we need to understand what a whole-tone scale is. A whole-tone scale consists of notes that are all separated by whole steps, meaning there are no half steps in between.
To find the different versions of a whole-tone scale, we can start with any note and build the scale by moving up whole steps until we reach the starting note again. However, since there are 12 notes in an octave, we can only have a maximum of six different whole-tone scales, as any more would result in repeating notes.
Let's go through each starting note and count the different versions of the whole-tone scale:
1. Starting on C: C - D - E - F# - G# - A# - C (One version)
2. Starting on D: D - E - F# - G# - A# - C - D (Second version)
3. Starting on E: E - F# - G# - A# - C - D - E (Third version)
4. Starting on F#: F# - G# - A# - C - D - E - F# (Fourth version)
5. Starting on G#: G# - A# - C - D - E - F# - G# (Fifth version)
6. Starting on A#: A# - C - D - E - F# - G# - A# (Sixth version)
Therefore, there are six different versions of the whole-tone scale.
To determine them, you can start on any note and move up by whole steps until reaching the starting note again. Note that all the notes in these scales are sharp because a whole step above the starting note will always give you the next sharp note in the chromatic scale.
