What F7 is made of
F7 (F seventh) is built from the notes F, A, C, Eb, with the interval pattern 1, 3, 5, b7.
Stack 1, 3, 5 and b7 on a root of F and you get F, A, C and Eb. That interval recipe is what makes the chord a seventh chord — move the same shape to another root and the character travels with it, which is why C7 sounds like a transposed F7.

Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with E♭ rather than its enharmonic equivalent.
