Molecular Forge

Trace atoms connected by covalent bonds to assemble named molecules (H₂O, CO₂, CH₄ …).

Goal

Build the target molecule. Element types and bond counts must match exactly.

Controls

• Drag from one atomConnect to a neighbour with the visible bond
• Single bondCounts as one shared electron pair
• Double / triple bondWorth 2× / 3× — needed for CO₂, N₂, etc.

Scoring

• Exact molecule → ⭐⭐⭐
• Right elements, wrong bond order → ⭐⭐
• Wrong → 0 stars but earns retry
