The ending '-chen' is a diminutive form. A 'Tröpfchen' (droplet) is therefore a small 'Tropfen' (drop). All nouns with the ending '-chen' are neuter and have the article 'das'.
Ein einzelnes Tröpfchen fiel vom undichten Wasserhahn.
A single droplet fell from the leaky faucet.
'Tröpfchen' (droplet) is often combined with the type of liquid, for example as 'Wassertröpfchen' (water droplet) or 'Regentröpfchen' (raindrop). Typical verbs are 'perlen' (to bead), 'hängen' (to hang), or 'sich bilden' (to form).
Am Morgen perlten unzählige Tautröpfchen auf den Grashalmen.
In the morning, countless tiny dew droplets beaded on the blades of grass.
The word is not only used for rain or dew. In the medical field, people speak of a 'Tröpfcheninfektion' (droplet infection) when diseases are transmitted through tiny liquid particles in the air.
Beim Husten und Niesen verbreiten sich feine Tröpfchen in der Umgebung.
When coughing and sneezing, fine droplets spread into the surrounding area.
drop
'der Tropfen' and 'das Tröpfchen' both refer to a very small amount of liquid. 'Tröpfchen' is the diminutive form of 'Tropfen' and emphasizes that the amount is especially small. It can also sound a bit softer or more vivid. 'Tropfen' is more neutral and fits almost all normal situations. 'Tröpfchen' is used more when you want to emphasize the small size, for example with fine water mist or very small particles of liquid.

Auf den Blättern lagen am Morgen viele kleine Tröpfchen.
In the morning, there were many small droplets on the leaves.
Am Wasserhahn hängt noch ein Tropfen, obwohl er schon zugedreht ist.
There is still a drop hanging from the faucet, even though it has already been turned off.
