Ground State Electron Configurations:
F : [He] 2s2 2p5 (no s valence electrons only p's)
K : [Ar]4s1 (1 of them)
Mg : [Ne]3s2 (2 of them)
B : [He] 2s2 2p1 (no s's, only p's.)

Potassium has one valance electron in an s orbital.
Fluorine has seven valence electrons; two of them are in an s orbital and five are in p orbitals.
Magnesium has two valence electrons, both are in an s orbital.
Boron has three valence electrons; two of them are in s orbitals and one is in a p orbital.
