One difference between a whole tone scale and a pentatonic scale is that a whole tone scale has 6 notes per octave while a pentatonic scale has 5 notes per octave. Another major difference is that a whole tone scale has all adjacent notes a whole step apart, while a pentatonic scale does not consist entirely of whole steps, and since a pentatonic scale is only defined as a scale with 5 notes per octave, there are many pentatonic scales that are possible.
Whole-Tone Scale
There are eight notes (steps) in a major musical scale. If whole steps are tones and half steps are semitones, then the order is tone, tone, semitone, tone, tone, tone, semitone.
It's called a whole-tone scale. An example is C D E F# G# A# C.
The tones within a scale are divided by either tones or semitones. In a major scale, the order always goes: tone, tone, semitone, tone, tone, tone, semitone. For a minor scale, in natural form, the order always goes: tone, semitone, tone, tone, semitone, tone, tone.
Yes it uses the whole tone scale as there are no semitones in the melody. You are right.

I'm not sure exactly what you mean by how many steps but I can explain a whole tone scale for you. A whole tone scale is comprised of all whole steps. For example: A B C# D# F G A or Bb C D E F# G# A# (which is Bb) So I guess there are 7 notes in the whole tone scale if that was what you were looking for.
Whole-Tone Scale
It is a scale made up exclusively of whole steps, as distinct from the standard western diatonic scale that is built upon the structure whole-whole-half-whole-whole-whole-half. For example, starting at E flat, the notes of a whole tone scale would be E flat, F, G, A, B, D flat.
The whole tone scale only uses full tones, therefore there are six notes per octave. Theoretically could can start a whole tone scale on any note but there are only 2 distinct scales. Whole tone scale starting on C: C, D, E, Gb, Ab, Bb, C Whole tone scale starting on Db: Db, Eb, F, G, A, B, Db Starting a whole tone scale on any of the other notes would merely be inversions of the scales mentioned above.
There are eight notes (steps) in a major musical scale. If whole steps are tones and half steps are semitones, then the order is tone, tone, semitone, tone, tone, tone, semitone.
You have described a Whole Tone Scale.
You can start the whole tone scale on any note. Say you start on C, then it would be C, D, E, F#, G#, A#, C Those are six different notes that compose one whole tone scale. If you start on C#, then it would be C#, D#, F, G, A, B Those are the other six notes that make up the other whole tone scale. You can start a whole tone scale on any note.
g - a - b - c# - d# - e#
It's called a whole-tone scale. An example is C D E F# G# A# C.
What ever note that is a major second interval below the starting note of the scale.
