📚 How to Build Ammonia (NH₃)

Goal: Draw ammonia - 1 Nitrogen, 3 Hydrogens, all single bonds

Step-by-Step Instructions:

Place a Nitrogen (N) atom on the canvas
Click "Single Bond", then click the N atom 3 times to add 3 hydrogen bonds
Select H from dropdown, click each gray placeholder to label them
Click "Check" to validate!

💡 Quick Tips:

Ammonia is similar to water but with 3 hydrogens instead of 2
All bonds are single bonds
Press N to select nitrogen, H for hydrogen
Press A to see bond angles - ammonia has ~107° H-N-H angles!
