Always Feminine
Even though it refers to a scientific object, 'molécula' is always a feminine noun. You must always use 'la' or 'una' with it.
The Stress Mark
The accent mark (tilde) on the 'é' tells you to emphasize the second syllable. This makes it a 'word with the stress on the third-to-last syllable' (esdrújula), and these always have accent marks in Spanish.
Gender confusion
Mistake: “El molécula es pequeña.”
Correction: La molécula es pequeña. (Remember that words ending in -a are almost always feminine in Spanish).
