B major scale

B – C♯ – D♯ – E – F♯ – G♯ – A♯

The B major scale runs B, C♯, D♯, E, F♯, G♯, A♯ and then back to B. It follows the major step pattern — tone, tone, semitone, tone, tone, tone, semitone — which is what makes it major rather than any other kind of scale.

It uses each letter name once, which is why it is written with 5 sharps.
