OH is not an element on the periodic table. Instead, it represents the hydroxide ion, which is a combination of oxygen (O) and hydrogen (H) with a negative charge (OH⁻).
Hydroxide ions are commonly found in bases (e.g., sodium hydroxide, NaOH) and play an important role in chemistry, especially in acid-base reactions. If you’re looking for oxygen or hydrogen, they are individual elements on the periodic table:
Oxygen (O): Atomic number 8
Hydrogen (H): Atomic number 1
