diatonic
The word is 'diatonic'.
The two intervals used to build major and minor scales are half steps and whole steps (also called minor seconds and major seconds). In the harmonic minor scale, an augmented second is used between scale degrees 6 and 7.
2 or two.
It is a mixed number.
Starting from the bottom: Whole step, whole step, half step, whole step, whole step, whole step, half step. The best way to think of it is all whole steps except for between the 3rd and 4th notes and the 7th and 8th notes.

No, songs can have major scales, minor scales, whole tone scales, etc.
Heptatonic means any scale with 7 notes. Diatonic scales are heptatonic, but they also have to have 5 whole steps and 2 half steps placed as far from each other as possible. The major and natural minor scales are 2 out of the 7 possible diatonic scales, but there are 792 (12! / 7! (12! - 7!) ) total possible heptatonic scales. You can play 7 of them on your harmonica (the diatonic ones), but probably each one only in a certain key.
There are 7 notes in a heptatonic scale. Heptatonic scales are the major and all minor scales including the 7 diatonic scales which are those consisting of 5 whole steps and 2 half steps separated by either 2 or 3 whole steps.
I will assume you are talking about a major scale on a piano, and the scales other than C major. (Similar answer for minor scales other than A minor.)A major scale sounds the way it does because of the pattern of half-steps and whole-steps. A C scale has half-steps between E and F; and between B and C. But suppose you start on a different note--D, for example. D to E is a whole step (so far so good). for the second to third, you need another whold step, and that takes you to F sharp. After the third is a half-step, shich puts you on G natural, then whole to A, whole to B; but from the sixth to seventh, a whole step puts you an C sharp. Finally, the half-step back to the root puts you on D natural.
whole tone
2 or two.

It is a mixed number.
a musical interval composed of three adjacent whole tones.
one whole, one half
