Add Explicit Hydrogens

This action transforms implicit hydrogen atoms to explicit ones.

(Explicit hydrogens are represented by connecting bonds to heteroatoms or carbons, while implicit hydrogens do not appear directly in the structure or are simply written together with the other atom.)

Example:

Action	Input	Output
Add Explicit Hydrogens(addexplicith)

Note : Some hydrogens may be already drawn explicitly in the input structure.

Use Remove Explicit Hydrogens action for converting explicit hydrogens to implicit ones.
