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.
