Cara mencari biloks dengan melihat muatannya
Mn = 0

 Bi^{2+} = +2

 S_{2}  O_{3}  ^{2-}
2S + 3O = -2 --> O selalu berbiloks -2
2S + 3×(-2) = -2
2S = 6 - 2
2S = 4
S = +4

CH_{3}
C + 3H = 0 --> biloks H = +1
C + 3 =0
C = -3

Ag = 0

Mn = 0

SiO_{3}
Si + 3O = 0
Si + (-6) = 0
Si = +6

 K_{2}  CrO_{4}
2K + Cr + 4O = 0 --> K biloksnya = +1
2 + Cr + (-8) = 0
Cr - 6 = 0
Cr = +6

 Cl^{-}
Cl = -1

 O^{2-}
O = -2
